I'm currently writing an overlay for our installation. All I have done
currently is a basic shell that just intercepts searches and responses
and passes them on (e.g., no processing of any kind is done). When the
overlay is enabled I see a 25% - 30% hit on performance. As I add code
to the overlay I'm sure the performance will degrade further.
Performance is a big deal for us since each slapd process handles
upwards of 15 million requests per day.
I read on this list a few months back that OpenLDAP 2.3 has
improvements in the overlay support code. Do these improvements
address performance issues at all?
