Comment 2 for bug 368023

Hardware
--------

I'm testing on a fresh checkout / buildout on a box with dual-core,
1 Ghz AMD64 CPU::

 $ cat /proc/cpuinfo
 ...
 vendor_id : AuthenticAMD
 cpu family : 15
 model : 107
 model name : AMD Athlon(tm) 64 X2 Dual Core Processor 4400+
 stepping : 2
 cpu MHz : 1000.000
 cache size : 512 KB
 ...

Running 'ab' locally with concurrency 4 across 100 requests, e.g.::

 $ ab -n 1000 -c 4 -A staff1:staff1 http://localhost:6543/communities/

The times I'm reporting are from the two "Time per request" fields in
ab's output: the "raw" number and the mean per request.

Case 1: start_over site with /communities/somecommunity added.
