Very slow on SDCard with partitions

I will apologize if this has been asked before. But I have been search for while and still have no clue.
The situation is: I normally run android with haret on sdcard without partition. (Thanks to all the developers). Every build is very fast except the most recent mssmison eclair (the new way). So, I tried to run the mssmison eclare on sdcard with partitions. It turns out to be even slower. I then tried most of the other releases which were fast without partition. All of them became very slow on partitions.
I guess it is possibly because I have a sd card without any "class x" label, (maybe class 2). But anyway, shouldn't android be faster with partitions than w/o?
or is there something related to permission fix?
Here is my settings:
Htc vogue
3 partitions: fat32+ext2(system)+ext2(data), I also tried fat32+ext2(system)+ext2(data)+swap, all very slow
Thanks

make sure you are choosing the right options in the installer. if you have system.img and data.img in your /andboot folder, then you are not running off the ext2 partitions and choosing the wrong default install location options.

After install , I have no sytem or data in my /andboot or /android folder. The system is renamed and moved to a backup folder by the installer. with the new way, I can choose where to put the system and data, "system on sdcard" and "data on sdcard", which are default, are selected.

Yes I also noticed that Eclair wasn't running fast even though I was using two Ext2 partitions. I didn't notice any speed difference between having the files stored directly in the android folder as opposed to Ext2.

definitely thought I noted a speed increase running on ext2 instead of regular sd card.

i really wana know which partition is better ext 2 3 or 4? n also if u can move songs etc to the partitioned space??

apps2ext+ question

I've installed a Micromod ROM , repartitioned my SD card and created an ext3 partition, so I do not have to worry about running low on memory on my phone. But I still see the amount of available Internal Memory going down. How is that ? I was under the impression that apps2ext would automatically put every app in the ext3 partition, isn't it the case ? Should I enable or change something in the setting of my phone ?
P_

Depending on Apps2ext solution that ROM is using, the dalvik-cache might still be on the internal partition. It will grow as you install more apps, albeit as a much slower pace. If the ROM is using the Darktremor scripts, you might be able to move dalvik-cache to either the ext partition on your SD Card, or to /cache partition of your phone (usually empty and is reserved for carrier's OTA upgrades).
App cache also resides on the internal memory. Moving it to ext partition is possible, but not recommended because it negatively impacts on the phone's stability. You can clear this cache by going to Menu -> Settings -> Applications -> Manage applications, and then going into large apps (sort by size) and tapping the "Clear cache" button. Cachemate can automate this for you.

[Q] what is app2sd and please can you help me activate it ? ?

what exactly is app2sd??
I am using RAFDROID ROM on a TMOUS HD2
in the instructions he said that if I am using a euro HD2 with 512 rom I should partition my sd card
so I did not do that and flashed the rom on my NAND
then when I started using apps I noticed that after two weeks usage I have only 50 MB left!!!!
so I want to activate app2sd and move my apps to the sd card..
so please I need some help from the experienced users on this great forum that can advise me about what exactly is this and how to activate and use it
thanks in advance!!

Apps2sd moves your apps to the sdcard, usually to an ext 3/4 partition. I don't know about the ROM you're using, but on the one I use (mdj's Cyanogen 2.6), you can move apps to external storage like this: settings --> applications --> manage applications. Then select an app and there is an option to move to sdcard.

@freeincolorado, the method you described is not A2SD+, that method is called move2sd.
A2SD+ puts the dalvik cache as well as the applications in a EXT2/3/4 partition, usually called the sd-ext partition. This method will still show you that the application is in the ROM. However, the sd-ext is used instead, depending on the chief implementing A2SD+ in their ROM, the remaining ROM space is suppose to report the partition "sd-ext" free space, however, certain ROMs are not properly done in my view, and will report the userdata partition free space instead. Such as MDJ's Cyanomodgen 7+ Gingerbread.
How to use A2SD+
Usually, they require you to partition your SD Card into 2 primary partition. The first partition is FAT32 where you store all your extras, such as music, ebook, etc (Like how your SD card is presently used). The 2nd partition is EXT2/3/4 depending on your preference, most people do not use EXT2 anymore as it does not support Journaling, since data can be easily corrupted with a battery pull. EXT3 and EXT4 contains journaling feature, so when battery is pulled, data corruption is minimal.
NOT ALL ROMS SUPPORT EXT4. This is a kernel thing, so if the rom uses a kernel that does not use EXT4, then it will not read the partition.
A2SD+ has a nice feature as well, when you switch ROM, you do not need to re-install all the applications, since all applications are placed in the sd-ext folder, including the dalvik cache. However, this also includes the system default applications which might not be compatible with another rom build.

[Q] How can I add a small Ext partition to my SD card and fill it with symlinks?

So I am an organization freak, and the root of my SD card had gotten a bit out of control. Not unusual, I know, but having just installed Titanium Media Sync and inKa File Manager, I've been doing a lot more file management and the constant scrolling through crap folders that I'll never need to access is getting old. So I've been trying a bunch of stuff to create what basically amounts to a folder full of shortcuts or symlinks that reference the various folders I need to use.
Now I could just create some sort of MyHome directory on my SD card and store my **** in there, but that doesn't solve the problem of having easy access to some of the folders that need to be in /sdcard, like the Download folder.
So the solution I came up with was to create a folder called 'Home' in the root of my phone. I added a bunch of symbolic links to Music, Photos, Downloads, Documents, etc, and the beauty is I can have stuff scattered all around my SD card and still access them neatly from this one folder. And filter out the crap I don't ever need. Doing this produced the exact effect I was hoping for, and I set it as my Home in InKa File Manager. However it comes with two problems:
First, this folder disappears every time I restart my phone! And second, even if this didn't happen I would still be faced with the folder disappearing every time I installed a new ROM. Oh, and in case it isn't obvious, FAT filesystems don't support symbolic links so this Home folder has to exist somewhere outside of the main SD card.
So, in conclusion: I would like to create a very small partition on my SD card that I have read/write access to, so that I can fill it with symbolic links that will stay put and always re-mount. My problem now is that I'm not familiar enough with the Unix file system or with mounting disks to determine how to make sure this partition gets mounted every time I start my phone. Or, if this happens automatically, where to look for the partition.
Thanks in advance to anyone who can point me in the right direction!! I'm pretty sure I have already created an ext2 partition on my card, by using iPartition on my Mac to place it after the FAT partition. But it won't let me name it so I don't even know where to begin looking for the partition itself.

Why can't you just make a folder called "Home" in /data somewhere? Shouldn't matter where the folder is since you can default your file manager to whatever folder upon opening.
Edit: Just tested it by making a folder /data/Home/
It survived a reboot fine.
Shouldn't be wiped when installing new roms either, as long as they don't wipe data like I know the ACS roms don't. Also if the rom you are flashing backs up and restores your data before flashing like some do, it MIGHT, idk for sure, but might backup this folder as well.

That... totally works. Stays after a reboot too. Thanks! This at least solves one problem and makes the idea totally doable again
Im still curious about a solution to the partition thing though. It would be nice to have a Home folder that was literally always around and that I wouldn't have to worry about even after installing new roms. I know some of them don't wipe data but I would generally Odin when installing a new ROM anyway. Installing Cyanogen for the first time definitely requires that and I feel like I may go back to a stock rom once or twice before CM goes final.

The reason nothing "sticks" when you put it in the root FS if because it is a RAM filesystem, loaded from a file image (zImage) at boot -- it's not a more typical file system in secondary storage like all the other filesystems. This is simply an artifact of how embedded linux systems work.

Resizing system and data partitions to take advantage of unused system space?

With a 32gb device and no option for an SD card, I've been looking at the extra space on the system partition wantingly.
I saw the option for resize 2fs is available in TWRP but have no clue how to properly use it to reconfigure the partitions. Also curious how this effects twrp backups and restores.
I've tried searching the forums and Google but haven't been able to find any how-to's or discussions about this that gave the information I'm looking for. Does anyone have any experience with this?

repartitioning is being done on many devices. see REPIT:
