After that many entries, slapd stops adding the entries to the index and instead
inserts a flag meaning all entries. Further adds to this key won't require a
write in the index file because the 'all entries' flag accounts for it already.

I remember hearing about a config flag preventing slapd to synchronize the cache
with the disk allowing it to work in memory, was this option used and would it
be fair to use such an option for your tests ?
