Web Map Service suddenly very slow?

[847396730]

I have a javascript application which includes a web map service which suddenly is unacceptably slow to draw on zooming in and zooming out (no query, just zoom).  I have confirmed that the request load is not maxing out the number of available instances, and given the quick response of both the SOA and basemap, have no reason to suspect the server itself.  I have also used the JavaScript Viewer directly from the REST endpoints and see the same problem, so the application is off the hook.

What else should I be looking for to troubleshoot this slow performance?

Thank you!

I would check your server.

Use task manager to see how much % ram is consumed, how many processes are running, etc....

We found a server that had some 200+ pkill processes in hidden cmd processes just hanging around and the 26GB of ram was at 87%.  They say if you get over 85% things will get slow.

We rebooted and things were much cleaner and faster after that.

May not do you any good but it's a simple thing to check.
