In java there is an optimal buffer size of 32 Kb which is based solely on the cpu architecture being used. On Android phones does the Dalvik VM dynamically know the proper cache of the cpu to get the largest buffer size independent of the many different phones out there? If so how would I figure that out at runtime?

Say I want to optimize a audio recording activity by making the buffer the largest it can be and also the fastest. I know you can get the minimal size for it but what about the optimal size?
