Thad,

 

Look at it this way: the output is telling you, that for the timeframe you
logged, your Fast Threads are waiting, on average, 1.1 seconds between
calls. and your List Threads are all waiting about 2.5 seconds. now, there
are periods of time when the system is really crunching, and there's very
little idle time (the MIN values). but, for the most part (the AVG), they're
acting like they've got all the time in the world (if you live in a world of
nanoseconds as CPU's do.).

 

Not knowing anything else about your system (like how long of a snapshot
this covered, how many users were logged in, how many CPUs do you use, how
much RAM, and several other factors), I'd say that it is a healthy system.
However, as I just pointed out, there are other factors that weigh into
that, which are, to us, the peanut gallery, an unknown.

 

So, long story short. the AVG is what I'd really watch.  :-)  (although, if
you note the MIN times on the List threads, you'll note that 6 of the 8 went
through a period of time where the calls to them were right on top of each
other (0.0000 MIN Idle Time = no rest for the wicked!), so it might be worth
looking at the API and SQL logs in detail to see what was pinging them so
heavily during that timeframe.

 

Good luck!

 

Matt R.

** 
Hello, 

I haven't had much occasion to use the log analyzer very much, and I want to
make sure I'm interpreting the results correctly as part of thread tuning.
In determining if I need to increase my threads, which column is more
important, the "AVG Idle Time" or the "MIN Idle Time"?  I can see it either
way and was hoping someone would share their experience. 

Thanks, 
Thad
