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
