OK, so I: * Changed my benchmark took to allow the test to be reported N times, and moved to microsecond timers. * Set up a fresh repository on a 1.6.15 server, with no post-commit triggers. So, with 10 iterations: ra_neon: 16.01 ra_serf: 15.94 Cheers, John. -- John Beranek To generalise is to be an idiot. http://redux.org.uk/ -- William Blake
