Hi Quanah,
Ubuntu 10.04 LTS Linux 2.6.32-43-generic-pae #97-Ubuntu SMP Wed Sep 5 16:59:17 UTC 2012 i686 GNU/Linux
The latest OpenLDAP 2.4.39
All of those tests done with the mdb backend, of course, and the actual file system is ext4
It's a fairly stock 10.04 system, no special config/kernel changes.
Ok. I had some wierd perf issues with Ubuntu10 and Ubuntu12. I was able to resolve them on Ubuntu12 by upgrading to a newer 3.x kernel (currently 3.10.11-031011-generic on my Ubuntu12 box).
Also, it isn't necessary to use ext4 (I use ext2 for the ldap data with mdb). ext4 in the 2.x kernel has some serious perf problems as well (when using writemap).
