$ make -jX iso_img TARGET_ARCH_VARIANT=x86-atom
It enables:
* SSE2, SSSE3 optimization (for memcpy, strcmp, ...) in bionic.
* Atom fast byte-code interpreter engine in dalvik.
The improvement is not very significant as expected,
but is better than nothing... :p
(check my blog for benchmark results)
Note the optimized image can only run on
an atom CPU machine (core i series is ok).
It cannot be used on older EeePC models
with Celeron M CPU (like 701, 900).
