This list is for discussions related to the development of
OpenLDAP software. Questions concerning the use of OpenLDAP
software belong on the software list (see list charters at

other vendors belong on vendor-specific mailing lists. General
topics (not specific to any vendor) can be posted to our
general list.
Please redirect your enquiry (and follow ups) to the most
appropriate forum. Do not cross post.

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.
>Or found ways to make it perform better under high load ?
See software list archives + FAQ.
>How about distributed setups with a caching proxy for example ?
We don't have a caching proxy (yet). We have replicas (with
caching).
