Not my app.

Original source: http://forum.xda-dev...d.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.

Nice find. I'll try it. How does it do what it does?

[Omar korom]

Great app , , have I to set the  " Enable RNGD entropy seeder " to yes ?

and what we do with rngd.zip ? and rng-tools_android.patch ?

[utternoob]

Leave those. Set that option to yes

[wizard.no.84]

I must say, I feel the difference..

[tilal6991]

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.

[utternoob]

Is it possible to integrate it into further builds?

[DJPRMF]

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..

[tilal6991]

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.

[utternoob]

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

[razzmataz1478]

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;

Remarkably faster on cfx3.

[zukenp]

Should we check start on  boot?

Yup.

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

Good find.

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.
