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"
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
