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...

Which hash method in userPassword? I'm writing this on a host which needs 12 seconds to do 27k crypt(password, "$md5-salt$hash")-calls.
I've been using cleartext and SSHA. SSHA gets about 4% fewer auths/sec than cleartext on this test system.
