OL 2.4 with howard and hallvard's patches: 17,086 auths/second.
I'm tempted to backport the patches to 2.3 so we can compare with
what 2.3 could have been:-)
That still leaves us over 4,500 auths/second (or 9000 searches/second)
slower than RE2.3. I.e., 21.5% slower. Which is quite a substantial gap.
Maybe --disable-debug is a place to fetch some speed. If it makes a
enough difference from loglevel 0, it might be an idea to disable _some_
loglevels and some asserts in the default build. After we've done
something about that broken log system of course - IIRC today one needs
to turn on massive logging to get certain error messages.
I'm running with loglevel none, which logs almost nothing. I do that so
syslog doesn't cause a perf hit. I don't think it specifically will make
much difference in the auth rate I'm getting.
