Kannst du vielleicht kurz und knapp sagen, was es mit dem Entropy auf sich hat?

Modulate OS entropy levels for lag reduction ala Seeder. The whole OS reads either /dev/random or /dev/urandom and both need entropy. However this mod uses a completely different, lightweight and efficient random number generator called Havege . This sharply reduces cpu consumption and corresponding battery life loss compared to Seeder. It also does a better job at keeping entropy levels high hence your device is more responsive. It doesn't run in a CPU intensive loop either. The extend queue functionality has also been added to CrossBreeder. See here for another rationale favouring Havege compared to Rngd - ( csrng - Cryptographically secure pseudorandom number generator - Google Project Hosting - Look for the limitations.)
Remove /dev/random as it's blocking . Link it to non-blocking /dev/urandom. Since /dev/random is blocking and designed to protect us from Quantum alien cryptographers with mathematical certainty and urandom is non blocking pseudo-random device that most apps and OSs are using anyway and with Haveged running, is as secure anyway as it's very difficult to empty the entropy pool faster than Havege can replenish it. Pre ICS devices have a lot to gain with this but ICS+ devices show visible gains too.
Frandom support - CrossBreeder now supports linking both your random devices to the extremely fast alternative - Frandom ( frandom: Fast and entropy saving random number generation for the linux kernel ). This module is orders of magnitude (10-50 times) faster than the standard character devices ( Check this out - http://forum.xda-developers.com/show...&postcount=134 ). The erandom character device also installed by Frandom doesn't use up system entropy at all on top of being fast. You will need to ask your ROM developer to develop the kernel module for you and then place it in /system/lib/modules. CrossBreeder will then try and load it and if successful, make all the necessary adjustments so that both /dev/random and /dev/urandom are pointing to /dev/frandom and /dev/erandom respectively. The speed benefits are to be seen to be believed. But since each ROM requires a unique kernel module, this option is left optional ( but auto detect ).
