It looks like from your stats that slapd has consumed all of the memory
given to it, and now has to swap. You need to adjust your DB_CONFIG file
so that there is more memory available to BDB, assuming of course you have
enough RAM for that.
Since you have dual CPU's, you could set "tool-threads 2" in slapd.conf,
Basically, if you want your slapadd to run quickly, you need to have enough
RAM on the system, and the DB_CONFIG file configured, so that the DB can
fit into RAM while being loaded. That's why my systems have 8GB and may
expand to 16GB before too long as we continue to expand the data in the
Is tool-threads documented somewhere?
