Hi Dieter,
I definitely read the man entries - for hdb it's more complicated, of course, but with mdb, my simple config came directly from the online docs.
My understanding is that there's really nothing needed/suggested for tuning parameters for mdb.
I've seen there's a 'checkpoint' option along with 'dbnosync' which can perhaps increase performance at the expense of reliability, but I wouldn't want to use that in production.
Using single inserts with auto-commit after each insert on Postgres on the same machine completed the same task in just under 2 hours.
I'd very much like to get my LDAP setup to add the entries in ~30 min, that'd be much more in-line with what I was shooting for on performance.
Any ideas to try very welcome.
Thank you,
Andrew
