[APP] Seeder - Reduces lag in Android.

Not my app.

Original source: http://forum.xda-developers.com/showthread.php?t=1987032

Install the APK, then open the app and enable it. Don't forget to grant the app superuser permissions.

It may be just a placebo effect, but my phone does seem a little bit faster now.

It definitely makes a difference. I'm pretty sure its not just placebo. I tested it on CFX3 and there seems to be a tangible speed improvement. The reason for it and the patch makes genuine sense as well.

Is it possible to integrate it into further builds?

I open the app and just appears two options. I enable, but after exit and enter again in the app, the option is disable again...

Is that fine?

The developer says you're allowed to so why not..

I think I'm going to have to. The speed difference I can feel is enough to convince me to include it.

Awesome, so it isn't just me after all.

I've noticed it on C3C0 CM10 ROM. Seems so much faster than stock, even in app draw

Very noticeable difference in PAC. Recent populate instantly, launcher is smoother and apps launch quicker. Well done to the dev.

Theres a few methods to acheive what should be the same result (entropy over 1300). For example heres an init.d script:

#!/system/bin/sh

# Entropy tweak

PSIZE=$(cat /proc/sys/kernel/random/poolsize)

PSIZE=$((PSIZE/3))

echo $PSIZE > /proc/sys/kernel/random/read_wakeup_threshold;
It should save battery compared to the application as it doesn't wake the phone at all and has no service running. -EDIT- You can also symlink:
#!/system/bin/sh

# Entropy tweak

rm /dev/random;

ln -s /dev/urandom /dev/random;
Or just recreate it as urandom:
#!/system/bin/sh

# Entropy tweak

rm /dev/random;

mknod /dev/random c 1 9;

Will it not reduce battery life due to hight CPU usage?. Please check this --> http://forum.xda-developers.com/showthread.php?t=1987032&page=86

The app 'works' because it uses a daemon process that "keeps the device's I/O in constant use (which in turn, depending on device, will make the CPU stick to higher clock frequencies to keep up and/or ramp up the IO scheduler)." - quote from a CyanogenMod developer

Remove the app and use the fix manually as above. Then see if you have an improvement or not.

Spanish people tell your friends over at HTCMania that this doesn't really work.

Makes sense I suppose, but saying it's like using the performance governor is just as wrong. It doesn't lock it on the maximum frequency like the governor does.
