Subject: Performance regressions in 2.6.30-rc7?

Hi, phoronix.com has run some benchmarks in 2.6.30-rc7 [1], there're some
good numbers, but there's also a couple of regressions. Some people think
that phoronix benchmarks are not very serious/reliable/meaningful, but i
thought it'd be better to post false warnings than letting real regressions
slip in without notice.

The regressions would be:
- 7zip MIPS ("7zr b" command) http://www.phoronix.com/data/img/results/linux_2630/1.png

- tiobench latency (not throughput) using 64MB writes with 32 threads

-gnupg 2GB file encryption http://www.phoronix.com/data/img/results/linux_2630/3.png
