PDAs, Cellphones, Wireless I've been flashing CyanogenMod 9 nightlies for months now, and the process to do so has become pretty much muscle memory at this point (if cwm ever changes its menu order I'm screwed). One step of this process has always fascinated me simply because I have no idea what exactly it does and why I have to do it: clearing Dalvik cache.

Dalvik doesn't do AOT compilation.

Though it definitely would be nice to add that.. There's no need to re-JIT the on-screen keyboard task every time it's loaded...

Having the code mmapped also reduces strain on the memory management (since filebacked mappings can be dumped to storage easily).

Would also create opportunities for expensive optimizations which could be scheduled for when the device is "asleep" and externally powered.

Essentially FX!32 for Dalvik.
