Hi Everyone,
We’ve inherited a 389-ds system (1.2.11.15-48.el6_6) that is running
on a VM provisioned with a single CPU. We have been experiencing high
CPU with a client that connects with a single connection, and then
runs large amounts of queries of the form:
SRCH base="ou=GROUPS,dc=<our dc>" scope=2
filter="(&(objectClass=groupOfNames)(member=uid=<loginname>,ou=EMPLOYEES,<our
dc>))" attrs=“1.1"
Trevor,
From the access log, what is the result of this search? etime? It
there a notes=U/notes=A in the result? It could be an unindexed search
which would cause the high CPU.
Thanks,
Mark
We’re wondering if adding extra CPU’s to the vm will make things
better. The original engineer noted that at the time of
implementation, he had come across some notes that indicated that the
underlying process was single threaded and adding extra CPU’s would
not make any improvement; in fact, on heavily loaded vm infrastructure
like ours, may make things worse as the the vm would have to wait for
the CPU to become available. Is this still true?
Thanks a lot,
Trev
