Comparing OpenLDAP 2.3.39 to RE24, 2.3.39 gets about 20.3K auths/sec on a 1M entry hdb database, vs 23.3K auths/sec for RE24 on our test machine. So about a 15% gain, most of which is probably the lightweight dispatcher. (Will have to test again with back-null to see for certain.)
2.3.39 back-null got 27k auths/sec vs 2.4(.7)'s 36k/sec. 33% gain, obviously back-hdb requires more CPU...
