See the software list archives and FAQ on how to tune OpenLDAP to
achieve such goals.

I suspect they (or any major LDAP vendor) could handle the above
load without much problem... though some scale better than others.
I assume they have a forum you can ask such questions in....

In general, >10 write-ops/second and >100 read-ops/second is
achievable using CHEAP pc-clone hardware (with tuning/configuration
to avoid write syncs). Scaling to 10M entries can be challedging.

See software list archives + FAQ.

We don't have a caching proxy (yet). We have replicas (with
