I have a nearly 400MB id2entry.dbb under OpenLDAP 1.2.11, and it takes
under two hours to slapadd it into 2.0.  Either something is wrong,
or you have some wicked substring indexes happening.  I have 30 index
files along with id2entry.dbb, but I use substr sparingly, because they
create large index files which are slow to generate.
