I am getting periodic SQL performance slowness, wait times. I ran the following query as I noticed some "PageIOLatch_ex" in the activity monitor. Does this mean I have a memory botttlenec or disk I/O problem? What other counters should I use to narrorw this down and possible remedies?
wait_type waiting_tasks_count wait_time_ms
