Actually, I have a utility that queries monProcessWaits on a short interval (3 seconds), saves the delta for each application process and lists out the processes with > .5 seconds wait time in the given interval. In general, I see a close correlation between a stored procedure running slow and the process invoking the stored proc waiting for event 29 (waiting for regular buffer read to complete). Does this event mean that physical io as opposed to logical io is being done? I also see a bit of 124 (wait for mass read to finish when getting page) and more of 251 (waiting for network send to complete). What is the difference between 29 and 124?
