This app displays the Random Entropy Available as presented in the kernel. 

This should be used alongside Seeder or in conjunction with your own performance testing.

There is currently some discussion the loading apps requires there to be random numbers available. 

I got the idea after reading over this forum post:http://forum.xda-developers.com/showthread.php?p=36359613I read up about random entropy seeding and I'm using the following values:

Performance changes:

Do not randomize address spaces: Performance Gain at loss of security?

busybox sysctl -w kernel.randomize_va_space=0

Minimum number to write random numbers: (Goal is 4096, so this is 25%.) Observed value 133  at beginning.

sysctl -w kernel.random.write_wakeup_threshold=1024

sysctl -w kernel.random.write_wakeup_threshold=4096

Minimum number to read random numbers: // gives it more time to read?

sysctl -w kernel.random.read_wakeup_threshold=512

Also interesting: I took a bunch of screenshots for this app release, and the number dipped down quite a bit..

    Good tool to validate seeder. Also good if you have seeder installed in a init.d startup script, as I do, instead if the app to check on the entropy.

    Apps dont get much simpler than this, but dont get me wrong, it does exactly what it says and it does it automatically. Thanks.

    I use it with the CrossBreeder mod/hack. It's like Seeder but has more options and AdBlock

    You can already see it on seeder alone

    Good app. Btw, where actually the entropy value come from? Is it from input pool, dev/random/ file, or /dev/urandom file?
