Terrible SFTP speed: 35KB/s - Nexus 7 Q&A, Help & Troubleshooting

Hi
On my Nexus 7 (2012), SFTP to my Mac on the same LAN using ES File Explorer reaches only 35KB/s. On AndFTP, I get around 200KB/s. How come the speed is so bad? If I FTP to the same machine from the same device, I get over 1.3MB/s on ES. How come SFTP speed is so terrible? I get the same speed on my phone too (Samsung S3).
Thanks

Low Wi-Fi speed on LAN

I've noticed the following problem:
When trying to download (file copy/video play) from my LAN to the HD, download speeds maximum is about 340 kbps (LOL...that's like EDGE) . With the same setup (wireless "G" router) I can download on the HD from internet with speeds 2 000+ kbps. LAN operations between my PCs/laptops are @ 60 000 kbps wired and 20 000 kbps wireless (using the same setup). To access my LAN from the HD I'm using Resco Explorer....and at that 340 kbps speed it's not possible to watch movies from my LAN. No such problem with my other PDA (iPAQ HX4700) which is not even "G" but "B" device - speed is about 3 000 kbps. Can anyone confirm this and suggest a solution? Can anyone watch movies from LAN encoded with more than 400 kbps?
p.s.: Speeds are measured using DU Meter (for PC)
p.s. 2: Same low (340 kbps) speed with another wireless router

if you are using the default memory card that came with the phone, it is only a class 2. the write speed isn't spectacular, this may not be the reason. but it's the only variable i see right now. since your can download stuff to your phone from web at good speeds. i think it's more of a problem with the machine that is "uploading" or hosting the video. check the upload speed of that machine.
I think the memory has nothing to do with the problem. And I've tried with different host machines - the same result.
Slow network speed through WIFI
I have to same problems on my HD. I am using a home server at home which holds all of my videos. When connecting to it and watching a video with my old Eten X800 everything works fine and runs smoothly. But doing the same on my HD results in an unwatchable video. If I copy and paste this video on my mem card on the HD the video runs smoothly. There are some strange things going on with the WIFI speeds on the HD
Anyone worth investigating this issue?
Yeah... the strange thing is LAN speed is much lower than Internet speed using same network equipment

The Host could be PC/another PC/Laptop - the results concerning the HD are identical, which means the problem is not from the Host nor the network setup.
Did you check the power saving settings in the WiFi parameters ?

YEAH!
it could be toggled/switched on "better performance" for better speed and "best performance" for g protocol. But the device will be hotter!

These settings affect both Internet and LAN performances but Internet speed is OK and LAN speed is slow. And yes, I did play with the settings - results are the same. (because I'm 2-3 meters away from the wireless router). I'll be glad if someone with HD, actually tests a connection between his HD and a PC in a LAN and not just giving "blind" suggestions. What I want to know is if it's a problem with all HDs or just my device is faulty.

the nerd in me just want to go to your house and troubleshoot this for you in person. LOL... anyway...
what is the file you used to test in each case? the reason i'm asking is that some files are more compressed than others, and the speed we see is the NOT the raw speed -- the capability of the wifi card. but the combined speed of the CPU processing power and the network speed.
long story short, if you are downloading, the data is broken up and transfered piece by piece -- a movie is broken up and transfered bit by bit. depending on the file, the receiver side needs to process these bits and recombine them back together. it's much easyer to recombine a webpage, text file or equivalent. but mp3s, rar/zip or movies are already compressed/encoded with special algorithm, so the receiver processor needs to chew through these data to recombine them, so it won't accept faster than it can "chew".
of course this may not be the reason for your problem at all, but try transferring a large text file (copy and paste text from a website to notepad and c+p over and over, till you have a ~ 10MB txt file).
Even on copy files (not trying to play them, hence no decompression) just copy from PC to HD, no matter what the file type is, the speed is that - 340 kbps. Why don't you just try it yourself?

Does it really improve speed? I find WIFI a bit slower with the yweak installed.

With my HD the same slow speeds. Tried several different hardware. Only HD is slow as hell. WIFI speed tweak does'nt do much, btw.
Some speed results:
WIFI Setting Best Battery / Resco Explorer 7.05: 45 KB/s
WIFI Setting Best Performance / Resco Explorer 7.05: 300 KB/s
WIFI Setting Best Performance / Total Commander/CE v2.51: 600 KB/s
So Resco does not work well with local shares. won't be using that anymore when c/p'ing. Altough speeds are doubling with TC it still is'nt fast imho.
Noone else tried this and encountered the same problem?
Ever find a fix for this?
I noticed the exact same problem last night when trying to play some TV shows over Wi-Fi from my PC. The file played OK for a couple seconds, then stalled
Using "Network Plugin for File Explorer" from HTC, I get an ave. speed of ±340kbps. The speed is the same whether I save to memery MC or phone memory. So the write speed of the MC has no bearing on the problem.
PS. Just tried on my work network with the same results...
Lucky you guys... I at best performance get ~120kb transfer and at optimal I get ~80kb transfer (copy) with Resco on wrt54gl with ddwrt on it

Wi-Fi LAN Transfer Speeds

I'd like to move video files from my Linux server to my Nexus 7. But I can't seem to get good transfer speeds. All transfers are over the LAN; no Internet hops involved.
Part 1:
I've tried using cafeFTP for SFTP and I consistently get speeds around 300 KB/s.
I've tried using AndSMB for Samba and I consistently get speeds around 400 KB/s (and Samba has file name issues).
I tried getting MTP to work, but it was really flaky; and I'd prefer a wireless solution.
My laptop (running Linux) transfers the same files via SFTP at up to 3 MB/s.
What kinds of speeds are people usually getting?
This is my first Android device so I have no other experience with Android transfer speeds.
Part 2
Best solution for transferring files from Linux to Nexus 7 without interacting with Linux machine (headless server)?
Also, does anyone have a solution that actually works to queue up a large transfer and keep trying until it's done? Both cafeFTP and AndSMB disconnect arbitrarily and then I have to reconnect and restart the transfers. This is incredibly inconvenient when trying to move a couple of movies overnight.
Misc. Info
My router is a WRT54GL running Tomato; I've been through its settings, but didn't find anything I thought would help.
I have done tons of searching about this; but there are so many garbage sites with no useful information covered in ads. I'm having a really hard time finding reputable information.
Thanks.

Showing 54 MB/s for both the laptop and the Nexus 7: Full 802.11g connection. Server is 100 MB/s.

Isn't 800 KB/s pretty slow for an 802.11n connection?
My laptop transfers the same files at up to 3 MB/s over 802.11g (shouldn't you be getting like 3x that on 802.11n?) . But I'm only getting around 1/10th that on my Nexus 7.
Using FTP I get ~2MB/s. Strange

Well 800 kB/s is slow even for wireless G which should go 2.5-3 MB/s.
As for N these devices don't have 40 MHz channels so rather than 150 Mbps they are limited to 65 or 72 Mbps link rate, which should translate to about 3.5 MB/s
well i wonder what my problem is then. I have a netgear N300 and my win 7 drive is hardwired to it with ethernet.
I setup a plain FTP server which is getting transfer speeds of ~2100 KB/s. So that's MUCH better.
Perhaps the Nexus 7 just struggles with SFTP (encryption overhead makes this understandable) and Samba (not sure why it's so slow, just cause Samba is lame?).
Guess I'll be doing all my transfers over FTP. This makes me much less grumpy.
Just to recap, here are the transfer speeds I was seeing over 802.11g (54 Mbs connection) from a wired server running Linux:
SFTP: ~300 KB/s (cafeFTP)
Samba: ~400 KB/s (AndSMB)
FTP: ~2,100 KB/s (cafeFTP)
Edit: Current hypothesis is that SFTP and Samba were both maxing out the CPU. I haven't checked with a app to measure it, but the tablet did get hot during those transfers. If that's the case it may be implementation specific and other SFTP / Samba implementations may be more efficient and achieve higher speeds.
Using ES File Explorer and logging onto my windows share, I got file transfers of 700-900KB/sec, pretty poor.
So I set up an FTPServer on android and FileZilla on desktop and I get around 2.8MB/sec on transfers.

Sorry for resurrecting a year-old thread but I just wanted to thank you for the suggestion of using FTP as the transfer mode as opposed to Samba. It's definitely a bit faster (~700-850KB/s vs 1.5-1.7MB/s). I don't know why you installed FTPServer on your Nexus 7 though, since ES File Manager is an FTP client as well.
I have the same issue:
During copy/move large file i.e. 2-3GB from Nexus 10 to Qnap NAS with ES file explorer I get max. 2.5Mb/s .
Is that normal or pretty slow?
My access point is this one: TP-link tl-wa901nd

There's a big difference between an FTP server and an FTP client. if you use a client on Android, you need a server on your PC.

What's normal on your network is whatever is normal for your network. We wouldn't be able to tell you since there's so many factors that could affect speed. There is something you could use as a sort of measure though: Try a PC-to-NAS file transfer and check what kind of speeds you get there. It's not a scientific way to do it by no means but it should give you a rough estimate of the speed you should expect on transfers to your N10.
I have a Galaxy S4 with the newest firmware from samsung I9505XXUGNF1 (Kitkat 4.4.2). My router is a Asus RT-AC66U to which My S4 connects to with max speed of 433 Mbps. My internet connection is 120 Mbps.
When I do a speedtest on the S4 I get results of over 110 Mbps, but when I'm downloading a file over LAN from the disk connected directly to the router I get download speed only of ~20Mbps (2.4 MB/s) which is very sucky!
My Laptop have only a N network card, and connects to the router with max 300 Mbps and when I download the same file I get over 7.5 MB/s!! (~65 Mbps).
Speedtest also shows results of over 110 Mbps...
I remember when the phone was new, and it had Android 4.3, I had LAN download speed of over 9-10 MB/s...
I tried with different file managers like X-Plore and others, but it looks like it is not the app problem.
Have you tried transferring a file over FTP?

[Q] Wifi speed copying from windows share

Hi,
i cannot get over 4 MB/s (32 MBits) with my N10, I tried to copy from windows share and windows FTP on my local 1 Gbit network over 5 GHz (300Mbps connected) Wifi. When I do the same with 2 laptops I get 20+ MB/s.
I used total commander and ES file explorer...
Has anyone tested this ?
Seems fine here, on my 5ghz network. I normally transfer movies this way. Though I don't check the actual speed, I don't think it is lower than 4 MB/s. Sometimes I even 'stream' full movies just by opening the file on the network through ES File Explorer. Even with really high bitrate videos it does not stutter.
I would suggest changing the client. Try Astro or Solid Explorer.

Weak WIFI speeds ~ 10-20 Mbit - Suggestions?

Hey!
Has anyone else had problems with their wifi connection?
My D802 rarely goes over 1,5 MB/s on SMB and rarely over 2,5 MB/s on FTP.
(ES file explorer, tried both 2.4 / 5 GHz, tried three routers atheros/broadcom AC + Linksys G latest firmwares)
Same wifi setup results in transfer speeds of 15-25 MB/s on two laptops with the current Netgear R7000 ac-router I'm on now.
Link speed in the G2 is shown as 433 Mbps. Running latest CM11 nightly 0224 rom but tried the original LG 4.2.2 with same result.
Is there a modem update or better app that can improve the transfer speeds? How about the official 4.4.2 update, does it come with any speed improvements?
I appreciate any suggestions you may have. /s
Just wanted to inform any reader that the problem was with the smb samba file explorer app. Nowadays ES gives around 5MB/s but the real speed champion is ...... Drumroll..... X-plore!
Winner by a landslide. Newcomer app that offers stable samba file transfers at over 9 MB/s. What a geek rush!

Lan transfer really slow after nougat upgrade

SMB file transfer is really slow after the upgrade.
All other wifi/lan transfers are fine. (FTP/HTTP/speed test/etc)
I am trying to copy files from my home NAS server using SMB/CIFS and it is painfully slow (2-300KB/s) where as FTP transfer from same NAS server is about 9MB/s. (Using ES file explorer as well as Total commander)
There was a same complaint from users of Note 7 but it went away due to the massive recall without getting resolved.
I have T-mobile version of the S7 Edge. Can someone with different S7 edge (U version?) that can test out SMB transfers and confirm whether your transfer speed is ok?
Is there somewhere that I can complain about this bug/issue? (official Samsung forum?)
Thank you.
You already posted that in the T-Mobile section...
Can't confirm that for ES.
Over there you wrote you've a 802.11g WiFi (54 MBit/s). With that you get at best around 6 MB/s and definitely not 9 MB/s.
Hi, I've got the same problem with you, have you resolved it?
After upgrading to nougat, the smb speed is only 500KB/s, before upgrading it's around 2MB/s though.
I have the same problem on my S8. No speed at all on SMB/CIFS. My S4 get 10 times faster speeds with same configurations. same nas, router, apps, etc.
It's not only with ES, also with all others apps I tried.

Hello,
I have the same problem.
According to this thread, the error also occurs on the S8:
https://us.community.samsung.com/t5...cpage/board-id/GalaxyS/thread-id/20261/page/2
Let's hope that Samsung fixes this with Android 8. Currently, I am staying with Android 6 due to this issue.
By the way, which file system are you using on your NAS? I am using XFS. Has anyone tried another file system on the NAS (for example EXT3)? I ask because I have been told that the bug occurs due to the XFS file system.
Best regards
