You should really put an index on objectclass Attribute. I'd guess your 
slapd is looking at each entry to check whether it is a referral, not 
using your indexes for searching at all. You can verify this by 
stopping and starting slapd, then doing a search on an indexed 
attribute, and a "fuser" on your DB files. There should be an open 
filehandle on the searched attributes index file.

That's nothing you have to worry about, AFAIK.

Well, the index, as I said. And you should run nscd, (If you don't do 
allready.) that saves a lot of lookups.
