New submission from dktc <dkruglyak+pypy at gmail.com>:

I just built fresh PyPy 2.0.1 and decided to run pystones test (from getting started guide) and 
compare the performance difference. To my surprise there is a significant regression:

v2.0.1    => This machine benchmarks at ~410000 pystones/second
v2.0.0b2  => This machine benchmarks at ~420000 pystones/second
v1.9.0    => This machine benchmarks at ~520000 pystones/second

Everything is averaged over many runs on the same CentOS 5 box. What could be causing this? Is 
this a real regression or maybe there are some build options that influence performance?
