Hi!
Another low-budget solution would be examining the syslog. There you should see the times when some bad thing is detected, the time when CRM makes an "execution plan", the time when LRM starts an action, the time when the action completed. In summary you could see where your time is lost.
Look for:
"crmd: [#]: info: do_lrm_rsc_op: Performing key="
"crmd: [#]: info: te_rsc_command: Initiating action"
"lrmd: [#]: info: operation"
"pengine: [#]: notice: LogActions:"
Maybe your configuration could be tuned.
Regards,
Ulrich
