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.
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
