[389-users] 389 LDAP Multi-threading question

[Justin Piszcz]

Hello,

 

Had an inquiry regarding ns-slapd, was multi-threading always supported from
the first public release?

I've seen ns-slapd (an older version) sit pegged at or near 100% CPU
utilization on a multi-core Xeon system.

 

I've read elsewhere that someone has seen it hit 200% on a 2 way Xeon system
(from 2007)

There are obviously other factors in terms of the DB, what you are doing, in
terms of add or add+delete; however was curious if there was an a parameter
or a compile time setting that enables/disables threads, if the default was
always to use multiple threads(?) or is it the case that there are other
non-optimized parameters being used that would not allow ns-slapd to utilize
the other N number of cores?

 

Justin.
