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
Did you try btrfs? I'd guess it could be faster for massive random writes.
It's a fairly stock 10.04 system, no special config/kernel changes.
Cheers, Andrew

Thanks, Dieter, Quanah.
I've been doing some experimenting with those mdb options.
I ran a few tests with inserting 10,000 records, wiping the DB in between, and changing just the one option at a time:
Base-line, no extra options: 4m8sWith "writemap" enabled: 8m55s
With "writemap+mapasync" enabled: 5m12s With "dbnosync+checkpoint 0kb/1min": 0m14s
I know you answered some of this before, but please update with:
What kernel? What OpenLDAP version? What Ubuntu release? What filesystem for the LDAP DB?
Thanks,
Quanah
