Re: performance on Solaris

I need to set up a LDAP production server with 800.000 entries.
Performance and stability are
my main concern, I expect around 250 binds and 50 ldapupdate/insert per
The machine is a SunFire6900 with 8 sparc US-IV+ CPUs and I'd like to
dedicate around 500MB
of ram to OpenLdap (more, if necessary). The OS is SunSolaris 10.
I'd like to know if OpenLdap is sincerely a good choice with these
numbers, and if anyone can
share his on-the-field experience with so many users.
250 binds/minute and 50 updates/minute is a very low number of each. You
fail to state what version of OpenLDAP you plan on using, or which backend
(sql, bdb, hdb, etc) so it's hard to give you anything concrete. Assuming
you'd be using OpenLDAP 2.4.21 + Berkeley BDB 4.8 with either back-bdb or
back-hdb, you should be fine. I would note however any testing I've ever
done using Solaris as the OS has been significantly slower than Linux
running on the same hardware.
If you have 800,000 entries, your main concern is definitely going to be
the RAM. 500MB is unlikely to cut it, but it depends on the size of your
entries. You may need upwards of 16GB of RAM depending again on how large
your DB actually is.
I.e., you fail to provide the data necessary to give you a conclusive
