Application Profiling

[Guest]

I'm posting this here and on the VS Forum.

I have an XPe system that runs a .NET (C#) app that works with external hw
via USB ports. The app consists of a number of C# DLLs plus wrappers around
the hw dll APIs (ie platform invoke.

On a 1 Gig system the system maxes out at 100% CPU usage.
On a 1.9 Duo system it runs at about 33% (total) CPU usage.

The code written by someone else needs some profiling etc.
I suspect there are some busy waits that are polling for events rather than
the sw being event driven. I am about to try to improve the app.

Q What tools should I use to profile the app. Any whitepapers or other
references?

Thx

You should also post this to the C# newsgroup.

I found some open source C# profiling links at:
http://csharp-source.net/open-source/profilers

Haven't tried them yet

There are also the XP performance monitoring tools that I could use.
