Lock response times

From Meta, a Wikimedia project coordination wiki

Re: Suggestion for better response times on wikitech.

See also graphs of the min/mean/median/max times: Media:Lock-times.png

This testing is I should stress _extremely_ naive. I used 'ab' to hit a single page from my test setup, which page is cached, so the work comes in checking the database for newtalk and the page itself and decompressing the cached page for the benchmark, which doesn't advertise that it can read gzipped data.

Machine is an Athlon XP 2400+ w/ 512MB ram, running FreeBSD 5.1, Apache 2.0.46, PHP 4.3.2 with PHP Accelerator 1.3.3r2. I ran the tests with this script:

for clients in 1 2 5 10 20 50
do
  echo "**** Testing $clients simultaneous clients ****"
  ab -n 500 -c $clients -k http://wikitest/en/Main_Page
done

The client and server are on the same machine, and there's a bunch of X junk sitting there running in the background eating up memory. I ran two runs 'plain', one before the lock tests, one after. The lock system was tested with limits of 10, 5, 2, and 1 processes. The server's MaxClients is at 150, way more than I tested. No images or stylesheets or anything were fetched.
