Check Random Entropy Available
Free AppAbout Check Random Entropy Available
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=36359613
I 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..

My entropy is 4096, everytime. Idk if this is because of the app or maybe because of v6 scripts.

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

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.

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

Good job, simple tool, there are flashable zips out there better than Seeder so this app is absolutely relevant when I want to avoid accessing info through terminal. :-)
