V8bench Info
This info is for v8-v5.
v8-crypto
Almost all the time is spent in the function am3(), which is an integer arithmetic kernel that operates on arrays.
JM generates good code for am3().
Type specialization (Crankshaft/TI) is expected to give a big perf boost here.

v8-regexp
Description. Numerous kernels stuck together. A collection of regexp operations gathered from 50 popular websites, lightly modified, and run in succession.
Key features. Ninety-four different regexps are used in many calls to RegExp.exec() and String.replace(). The return values of these calls are never used.
Mozilla-specific things. We convert RegExp.exec() to RegExp.test() if the result isn't used, or is only tested for null (bug 581595). This speeds the test up by about 1.8x.
