...And what version of openldap are you running again? 

2.2.23 (The version in Debian Sarge). Debian hasn't even gotten to 2.3.x
in unstable yet.

Well, dump the debian version. Either build 2.3.20 yourself, or use a free pre-compiled version like CDS silver (at http://www.symas.com). 2.2 is historic, and that particular release of 2.2 had a number of bugs. A lot of performance tuning was done later in the 2.2 series, and in the early 2.3 series. You won't get those benefits running that old of a version of OpenLDAP.
