Splitting up your DIT can give some performance improvements if you
have separate storage for each part.  back-meta may also give you some
flexibility options.  You may also want to review your indexing
options.

Solaris 9 started huge updates to the disk system and Solaris 10 keeps
it going.  (Although they were always faster than linux, in my
opinion)  Upgrading to Solaris 10 will give you a boost for free.

If you want to stick with solaris 8, there are a lot of articles out
there about tuning solaris disks with fsflushr-related settings.  Look
at docs.sun.com for solaris 8 /etc/system tunables.  Even if you
upgrade, you should look into your OS tunables for such an I/O-intense
service as ldap.

Probably.
