I have made changes such that backend BDB ( ver 4.5 ) resides in

I was hoping to have a better performance with this.
back-bdb as currently residing in HEAD already yields efficiencies of 95% of
available system bandwidth. It is extremely unlikely that you are going to be
able to improve the performance significantly, most changes you could make to
the code at this point will only yield performance losses.
But what I now see
is that do_add takes much more time then what it use to take when BDB
was on-Disk. Indexing is done on objectclass in both the cases.
Any pointers on why this could be an issue?
