I had my HTC Desire which has 512MB of RAM.
on stock froyo rom i have managed to have around 300MB free while on rom's with sense around 220-250mb free after boot
on galaxy i have around 130-160mb top after boot. WTF?
The desire actually has 576mb of ram, which partially explains the difference. Don't know about the rest, maybe poor optimization of the touchwiz interface.
thats because of poor memory I/O management by Samsung.....
thats why you see lots of lagging complaints by end users....

It's 100% guessing, and my bet is that it's the same amount of bullcrap. The lag is likely caused by many running apps, but for entirely different reasons than poor memory management. Samsung has no reason to fiddle with the memory management implemented in android, so I'm quite confident they didn't because it would be a waste of time.

Then why would it lag like hell fresh from the box without any form of tweaking or installing apps?

because the lag is caused by slow internal storage also.
That is why the best fixes for lag involve moving things to external sdcards

If I knew I'd tell you.. I'm not going to pretend that I know how the SGS is designed. Could be poor CPU-throttling, power management issue, maybe the sole cause for the lag is a poor gps driver that hogs up too much of a specific system bus... I have no clue, but there are tons of ways to make a phone lag that doesn't have alot to do with memory management.

Have any of you tried to flash to a newer firmware?
With JM2/JP3 you can see 305mb (rahter than the 256 of stock JF3), and the free memory is usually between 200-230mb.
We're supposed to see beter Himem memory in the final builds of froyo, resulting in more available memory, though endeed a large part of the 512mb is reserved for radio/gps/wifi/bt and other system uses.
I put on the new Voodoo Lag fix and have had no problems. My phone is as fast its ever been. Because before that I was using ryanzas lagfix on the market and kind of made my phone faster. So I removed ryanzas and put on the voodoo, and found I could still apply ryanzas, so I did and my phone is super fast. At least I feel like its faster. So for the devs I know this isnt a q&a but is this actually working, and can u guys apply this into ur future work?

curious what tests have you run to determine it is indeed faster? I need to go back and read through Ryanzas lagfix but from memory I thought it created an EXT partition just as the Voodoo lag fix does.
If this is the case there would be no speed improvement as your system is only using one EXT partition so running the 2nd lagfix does nothing or changes the size of the EXT partition created by Voodoo.

Ok so all I do is try to make my phone faster when I have time. But I partioned my sd on my mytouch with amon ra then I put my sd on ext 4. Than I ran the voodoo lag fix using the the deodex rom. Voodoo lag fix put my quadrant scores at 1700 about which seems realistic. Because with ryanzas I was getting 2400-2500. But I only had 500mb of app space left bcuz of the partition. But after voodoo I have 1.4mb and I ran ryan zas on top of that and I have the same 1.4mb left. I think I can run both because the voodoo lag fix is a system partition and ryanzas is only virtual. At least thats what I think thats why im asking for help. But I run about about 2000 to 2100 on my quandrant scores and my phone has no lag at all.
I say try it if u can because my phone has never been faster. I dont know why it works but I believe it does because I can see and feel a difference in the phone. Everything runs so smooth. Its fantastic!!!!
Why stop there? Install another lagfix and I'm sure your phone will be 3X as fast!!!

Rsfaze already explained to you why it wouldn't, both of the fixes do the same thing and by doing the same fix twice they do not combine to give you double the benefit.
Imagine your hard drive is fragmented and your PC is slow, well you defragment it and it becomes faster. What you are essentially saying is that if you keep on defragmenting it it will continue to become faster which is ludicrous, unless you can post a quadrant score of 3000
Iirc the virtual ext lag fix simply cached some of the data for quicker access, and that's the increase you're seeing.

Ok true, but arent the lag fixes different? They arent set up the same and put on different ext's
And why did it improve my quadrant scores? and usually the phone wont allow u to apply two
Lag fixes at once when they are the same thing. Because I am using the lag fix apk and the voodoo lag fix through rom manager. Try it and tell me what u think?

Hey man, if those placebo pills work so well for him, don't stop filling his prescription.
Well i honestly dont know the details behind it but I can say that my phone does feel faster. So try it for yourself and tell me what you think. It is perfectly safe and you can always remove it. But just apply the voodoo and then go on market, and get ryanzas lag fix and apply that too. I am using the deodex rom so I dont knkw if that makes a difference. But thx for explainations. Later

Haha, I seriously doubt this works, run 4 quadrant tests, the first being stock with no lag fix, second with one of the lag fixes, third with only the other lag fix that you did not use before, and lastly run a forth test with all of the lag fixes and post all the scores generated by quadrant.

Stock odin 900
Ryanzas one click 2400 not believable but thats what quadrant says
Voodoo 1700 can see a real difference
Jacs kernal and no wake 1400 can feel diffrence mainly bcuz of overclock
Voodoo + ryanzas 2100 feels smoother and faster than just voodoo
Dont believe me than try for yourself.
If quadrant says so I believe it, though I am not able to try it I'm running the new leaked rom, I don't believe that is compatable with the voodoo lag fix.

Well the quadrant scores are just quadrant scores to me. I just go off of how many phone feels and what it does and it has never been snappier, my bro has same phone and he has the vodoo lag fix and we did a side by side comparison and mine was faster so I will let the people be the judge and let them try for them selves.

The voodoo lagfix uses ext4, which is a little slower but far safer. By installing ryan's virtual ext2, youve merely regained ext2's speed at the expense of ext4' safety along with the improvements gained from an optimized kernel.

Ext2 has a faster write but Ext4 has a faster read when tests where done on the two. You already mentioned the safety of ext4 which would be the journaling that Ext2 does not do.
I still don't think ext2 would be faster than ext4 but I could be wrong.

I've had that happen on my Eris, so I just chalked it up to being "normal."
It's certainly far from being normal, it never happened on my Droid 2, Incredible, and rarely on my Droid. It's unacceptable that a 1ghz processor should struggle so hard, especially after being called the strongest processor. It seems whatever tweaks they've done severely affect multi-tasking in general because it happens all the time now that I think about it.
This should be fixed with froyo. But this is what the lagfixes are for. There is the OCLF n the market, run it at 700mb(u will c what I mean if u use it) it will not lag at all anymore. Then do quadrant. Its a little bloated but shows the true potential. Try it, post back
they call me...kick ass
I had this happen to me on my incredible too, but that was after I had it for almost 6 months.

I'm guessing you're seeing the effect of the poor performance that Samsung's proprietary filesystem offers. That's a disk I/O problem, not a CPU problem. The lag fix partially fixes this by creating a virtual ext2 filesystem, but not everything goes on that filesystem. The apps themselves are still installed on Samsung's filesystem, so the larger the app, the more "lag" you'll notice as the system waits for the data to be written. Hopefully they will change the filesystem with the Froyo upgrade, but I wouldn't count on it. Best hope for fixing that is probably a custom ROM.

How do they make things worse? You can't be serious? I mean, some of them may not cure it completely (though I reckon the voodoo one seems so far to get pretty close at least), but they definitely don't make things any worse than before the lag fix.
I have to say that i have OCLF that turns your file system into a ex2 instead of the stupid proprietary file system that samsung used and it's faster than a lightning right now.
Have it for a week now and it's running smooth so far.
I wonder if there is any logic explanation for Samsung to use the proprietary RFS filesystem instead of the regular ex2 or ex4? It's reallyyyyyyyy a bigggggggggggg difference on performance.

I haven't had this problem, but... couldn't you just undo and then redo the lagfix after 2 weeks if it's slowed down for you? Then it would be fast again, right?
JPK was still just a little too buggy for me, nothing has come close to JM8+Voodoo in my experience. Also to the guy saying that the lag fixes make it worse, you obviously haven't tried voodoo, it perfects the SGS by converting to the file system the phone should have had in the first place.

Many you should sell the phone and buy a iphone.
Lagfix do work. If they don't work then its because you have done something wrong with you phone.
A had lagfix on it with 2.1 and i did it when i upgrade to 2.2. It was the first thing i did so i knew that i did NOT had anything that would interfere with it.
All working super. No lag.

+1 lagfix is overrated. My wife's sgs is running on voodoo, and she complains of lag after about a week. Ran quadrant and score is only 1200+. Reboot her phone and it's snappy again. Quadrant score shot up to 1708. I reboot mine everyday and never have any issues with lags. So regardless of what lagfix you applied, nothing beats a regular reboot.
When I had just over 50 apps installed, I noticed a real lag issue, especially when trying to access any of the conventional phone utilities, like phone, contacts or messaging. Quadrant was returning a score of 851. Installed RyanZA OCLF after reading about it on here and I can confirm that there were no issues, worked like a charm. Quadrant score was now 2265 and the phone was noticably zippy. I dont tend to switch the phone off and have noticed the phone starting to lag a bit (after about a weeks use) however, a quick reboot and its just like when I first installed the lag fix.
Appart from the lag fix and of course root access, the phone is still standard with Eclair XXJM1.
LAg fix works man . . . i am on JPK with lag fix its works

She was already on autokiller on strict setting. I am beginning to suspect this is an android problem. All my friends on android phones experience lag after some time of usage, including desire
So I am wondering what others opinions are of the roms and kernels available for the SF. Doesn't seem to be much of an improvement on Quadrant scores utilizing another rom or even stupidfast kernels.
Are we just kind of screwed a bit until 2.2? Is there a kernel that is overclocked?
TIA.
Quadrant scores are mostly meaningless, and 2.2 is unlikely to be revolutionary. The phone performs well on 2.1 - keep reading the forum and you'll get there.
In my opinion the biggest performance increases ive seen werent in any benchmarks but in dj05. it runs amazing. If u havent tried it i dont know whether you should or not. With the impending froyo release no one knows if they are actually going to release DJ05 or not. I think they should release it and then put froyo on top of that foundation if at all possible

What do you feel about DJ that helped it out?
I finally stayed with just a Voodoo lag kernel. There certain operations on the phone I had gotten used to that were slow. The kernel with lag fix did show me noticeable improvement, more than just a higher I/O score in Quadrant.
I think the phone is fairly solid on 2.1 but needs a little help. Hopefully the Froyo upgrade really is around the corner but Im not holding my breath

Yes benchmarks dont mean too much. But they are a good indication of overall performance in their specific areas that they test. As they fascinate test well in every area except i/o.

@Joe: same setup here (DJ05 deo, Stock Kernel and Rom, Frozen bloat in Titanium) without SetCPU. It's FAST. My GF and both my sons have EVOs running 2.2 and my Fascinate is just as fast (or faster)
@ksizzle: I agree, it's hard to quantify exactly what is so good about it. I think it's not what's there, but what's NOT there (lag) I think there are going to be plenty of happy n00bs when the OTA hits. This phone will be a screamer right out of the box!

Actually, the real performance difference between 2.2. and 2.1 is very revolutionary, though I certainly agree with you about the irrelevance of Quadrant scores. The Java virtual machine, for example, executes code 450% -- that's not a typo -- faster, which directly impacts most apps.
And, 2.2's browser is also significantly faster than 2.1's -- and iOS4's, for that matter.
I like my Fascinate, and yes, I would consider it fast (especially running DJ05 with Geeknik's kernels) but like many others, I too see slowdowns sometimes that just shouldn't happen with the phone's hardware. Froyo isn't a magic pill, per se, but it should significantly reduce or eliminate those slowdowns (as it did on my old Droid 1, despite it's far-slower processor).

Fixed that for ya. Don't let marketing hype get the best of ya.
Everything I've read states that the performance improvements between 2.1 and 2.2 have little effect on Hummingbird processors (which is what is in all Galaxy S phones), and the biggest performance gains are seen on Snapdragon processors. As far as performance goes, I'll believe it when I see it.
