I'm working on implementing groups in our directory server. We have a
large number of groups, many with a large number of members. I've
noticed that when populating a large group it starts taking longer and
longer to add a member. For reference, I've included my current
DB_CONFIG. At the bottom of this message is a table containing
measurements from populating a group of almost 20,000 members. The
first column is elapsed time, then total number of members, number of
members added in the previous five minutes, rate per minute, and
finally rate per minute averaged over the last hour.
