Did you make the changes to the DB flags for MDB that I noted the other day? For me, MDB writes are a minimum of 65 times faster than writes with BDB/HDB, even when BDB/HDB use an SHM key.
Yes. I have these values in my mdb configuration: olcDbEnvFlags: writemap olcDbEnvFlags: nometasync
I think these setting may have helped to speed up slapadd, but not ldapmodify.
I'm specifically talking about ldapmodify actually. ;)
