ColdFusion Performance Debugging
Article 8627
This article describes ColdFusion Performance debugging techniques on both
the Windows NT and Solaris platforms.
Some of the most difficult ColdFusion problems to diagnose are performance
and stability issues. This is due to the fact that there are many factors
that effect both performance and stability of applications. This document is
broken into two sections:
I. ColdFusion Thread Processing.
II. ColdFusion Performance and Debugging Techniques.

> We've been having a similar problem. We've turned off scheduled tasks,
> upgraded ADO (to 2.6), traced all sorts of things.
>
> The problem we have is that the unresponsive thread count climbs up and
> eventually kills the server. We have two processors and have noticed that
> one processor will be maxxed while the other is idle. The processors
> alternate in activity and the average is always near 50%.
>
> We're having to stop and restart cfserver twice a day to combat this.
