Nice. Tried it on my Defy running CM7. The phone was pretty snappy already, but now it flies. It's not a placebo as I did some runs with opening apps, using them, and such before and after. This for sure speeds things up.
[Android Software/Hacking General [Developers Only]] el_smurfo:
Dalvik dev says dalvik doesn't touch /dev/random. Google code thread closed. Common opinion appears to be that its placebo, either from reboot or keeping phone in higher CPU state. Seemed to work for me, but the compass funnies I had scared me off and after removing and a reboot, seems just as fast...maybe placebo, maybe not, but at least the dev is being upfront about the questions rather than a confrontational nut bag like certain other performance mod devs.
[Android Software/Hacking General [Developers Only]] bit2:
Using JB 4.2.1 on a Galaxy Nexus I executed "lsof | fgrep /dev/random" multiple times, but it never returned anything.

Executing "lsof | fgrep /dev/urandom" however returned tons of processes.

Is it possible that JB 4.2.* already uses urandom for almost everything and this seeder does no good at all for this OS version? :-o
[Android Software/Hacking General [Developers Only]] itznfb:
You obviously haven't tried this on a Galaxy Tab 10.1. I just tried this on my GTab and it's a completely different device. Running JB the device would become unusable after about 20 minutes. Now I've been running for several hours and it's performing better than ever. No placebo here.

Tried the apk on my desire z running cm 10.1 and it's half the opening times for the phone apk. Messages and camera. (From about 7 second to about 3 seconds)

[Android Software/Hacking General [Developers Only]] zeppelinrox:
If you have any init.d boot scripts, just add this in there somewhere

busybox sysctl -w kernel.random.read_wakeup_threshold=1376

Don't touch the first line (#!/system/blah/blah)

Make sure there's a blank line at the end before saving.
[Android Software/Hacking General [Developers Only]] jeremysherriff:
Yep, even helped Task's awesome ROM become more awesome. Substantially less laggy for heavy workloads, especially the android "recently used" list.

Correct. I don't know why anyone is flashing zips, an APK is much easier to install and uninstall. The app works as advertized, although you may not find any benefit for your device (works on all mine though). Just be aware that there is a bug - if you set it on, and then leave the app, the app shows the mod is disabled when you return. It isn't, just the gui has a bug.
[Android Software/Hacking General [Developers Only]] Flashalot:
Calm down

Just wipe and reflash next time don't flash some thing you don't want to flash

I'm also pretty sure it isn't the OP's zip, that someone else put together a zip afterwards.

Read the script inside the ZIP and see what it added/changed, and undo each step.

[Android Software/Hacking General [Developers Only]] mwalt2:
It's a .zip. Any modern OS can open it natively and you can see what is inside. That's all that is in the .zip. It's just a script that calls a program in /system/xbin on your phone. The only other thing in most flashable .zips that you might check is \META-INF\com\google\android\updater-script. You can open updater-script with a text editor and read what it does. Most of the time it just mounts /system, extracts the .zip, maybe sets permissions and puts some text on your phones screen :).

Before doing anything, please read the first post of this thread to understand how this thing functions!

Read it here: First post

And now for the way to clean up Seeder_v6:

Via recovery:

Flash Seeder_v6&7_Uninstall.zip:

http://www.androidfilehost.com/?fid=9390248398092764753

Via terminal:

1. Download Seeder_v6&7_Uninstall_non-CWM.zip:

http://www.androidfilehost.com/?fid=9390248398092764145

2. Extract it to the root of your sdcard (/sdcard), you should get a file named uninstall.sh

3. Launch terminal emulator and type this:

su
cd /sdcard
sh uninstall.sh

4. You are done! Everything gets cleaned up, including uninstall.sh...

You only need to download the apk and install it, but be warned, the app doesn't quite work right (all of the changes work and everything is functional, but if you go into the app, turn on the mod, back out of the app, then go back into the app it will say that the mod is off when it really is on.

[Android Software/Hacking General [Developers Only]] AglarondTX:
OK. I ran some more tests. I made the sysctl modification mentioned earlier and reboot. Ran the same tests i did before and found no change. I then disabled the random fill, rebooted and had no change. I then disabled both, rebooted, and found my tablet back to normal. Set sysctl again and everything sped up.

I'm leaving the sysctl change in place in init.d and removing the rest. In my case, it has the same effect and, in my opinion, is a cleaner fix.

Also, to someone else's point earlier, i found the same thing with very few calls going to random. Almost everything was hitting urandom already. Something else is at play here.

Even if it is safe for cryptography, it shouldn't really reduce lags in many apps unless those apps somewhy use /dev/random while /dev/urandom is enough for them (means that thos apps were written by idiots).
