[Q] Slow pc-to-phone usb transfer speed when using aokp - Galaxy S II Q&A, Help & Troubleshooting

Hi there everybody
I recently upgraded my phone to ICS aokp, more accurately, omega 3.0 rom and my usb transfer speeds from pc to phone have decreased drastically. I have an 32gb SDHC card class 10 that use to give me 10mb/s average speed transfer with GB and now it won't get over 4mb/s, if lucky. As for the internal memory, it won't get over 2mb/s and it used to be around 10mb/s as well. Transfers on the other way around (phone-to-pc) are better than ever, over 15mb/s.
Hope somebody knows a reason for this, a solution or a workaround.
Cheers

A quick look at the ROM page shows that the ROM has a mod called RemountSD. This stops you from being able to use mass storage to transfer files, only MTP works - this could be the source of your speed issues.

try to change the usb-cable

Nah, I've already tried that and it makes no difference. With or without applying RemoundSD, using MTP or Mass storage, trying other apps such as Dual mount SD ( I read somewhere that it worked as a workaround) and also changing the USB cable for a new one, the outcome is always the same, the pc-to-phone usb transfer speed won't go over 4mb/s when it used to be always 10mb/s.
Any other ideas of what could it be?

On CM9, I've got this too. On Mass Storage is insanely slow, but swiching to MTP will increase like 150% the speed.

Well, now it is going at about a third of the speed it was supposed to, I've tried switching to MTP too, also unmounting the SD or mounting it with the app that comes along with the rom, and the only thing I've got out of it is that the computer doesn't recognise the SD on its own, it opens the phone with the both main directories, internal storage and sd card, but the sd card appears to be wrong and won't open. In order to get to it, I have to open the internal storage, navigate to the external_sd folder and open it. Now, via this way I can get to it, but either way, the usb transfer speed is still about a third of what it used to be on GB, 4mb/s, never higher.

Try erasing the external sdcard on the Settings/Storage, maybe it's the file system error. But backup all your ext sdcard data, of course.

Nope, I doesn't work either, just tried that and my card won't even appear in settings/storage, its space is blank. Even though it doesn't seem to be there, it is and it works perfectly for everything in every other app, the only problem is that it doesn't write as fast as it should. In any case, I took it out and formate it all the same and put it back, etc, it is still the same.
Thanks for trying though

just saw the new omega rom 4.0 (AOKP built.37). I'm gonna give it a try and let you know if there is any difference.
I still find hard to believe that among all the people that has installed CM9/AOSP/AOKP roms, nobody seems to know any solution for this problem, talk about this problem or even try to give a possible solution/workaround for it.
Well, I'll keep trying since I really like everything else about the rom

---

Nah, I did install Omega 4.0 and it did improve the speed initially, but soon after that, after installing google apps, titanium backup and some other apps it gets slow again. I've tried different installation order just to check if it was any special app but it seems there is no link, at some point it just starts going that slow.

Working finally over MTP
Hi there again,
Well, I tried upgrading to v4.0, and before installing all the apps and personalising the rom, it worked, both on mass storage and MTP, the speed was around and over 10mb/s. However, after putting all my stuff together, it went back down again to 3.5-4mb/s.
Now, I read somewhere else that somehow my USB drivers could be in some kind of conflict with something else so I downloaded the last version and installed it and now it is working, only on MTP, but it goes up to 10mb/s again.
Thanks for your time again guys and your effort.
Cheers

I am having slow transfer speeds to the phone too, I tried reformatting my card and I still get slow speeds I dont eve reach 4mb only 1-2 mb and I am using a samsung class 10 card. But pulling items from the memory card to the pc is faster. I tried hydra ROM and RR Rom both give me slow usb transfer speeds.

---

im even experiencing speeds in regions of only 500 kb/s when im trying to transfer to my external card (class 6). but when im copying sth to my internal one it speeds up as always. is this the same with yours?
it seems to be the only way to change to mtp. but then im getting sometimes some weird errors when transferring to both cards.
im on slim ics.

I have the same problem. I am on Resurrection 1.8 right now, which is also aokp based. I have little understanding of 'mod'-s so I cannot tell if I suffer from the very same problem. Another problem is that in mass-storage-mode I can see only the internal memory, not the external.
So... 2 questions:
1. If the problem is the 'mod'... how can we fix it?
2. The common 'solution' for getting access to the external sdcard in mass-storage-mode is an apk called 'multi mount sdcard', but that doesn't work for me (don't know why...). Any other solution?
greetz & thanks in advance, FourthRock

Is Hydra also aokp based?
I remember that I did not have these problems when resurrection was not based on aokp...
