[rhelv6-beta-list] Apache benchmark RHEL 5 vs. RHEL 6

[Morten P.D. Stevens]

Hi,

here is a small apache benchmark between RHEL 5 and RHEL 6.

RHEL 5: Requests per second: 8790.99 (11.375281 seconds)
RHEL 6: Requests per second: 4863.53 (20.561 seconds)

What surprises me is that RHEL 5 is almost 90% faster than RHEL 6???

Here is the full benchmark:
