Sounds great, thanks Alex.
Interestingly, while 2 cores can get over 13,000 auths/second,
get around 25,000 auths/second (using back-hdb), with all 8 cores
peaking at 29,000 auths/second. This tells me it's better to run two
slapds in a mirrormode configuration on this box (4 cores per
process) than to
run a single process across all of the cores. Then I'd expect to hit
auths/second total, pretty close to the limits of the ethernet
Well, I guessed wrong. The peak with two separate processes was still the
same, 29,000 auths/second. Interestingly, the peak with only 6 cores was about
31,000 auths/second. It appears that we're memory bandwidth-limited.
