Slow load times and High CPU Usage on server.

[briandic]

I am very new to ASP.NET and it's quite possible there is some "not so optimized" code in my website. We are experiencing extremely slow load times and sometimes no load at all. There are 2 processes on the server that run the cpu at high volumes. I do not know where to begin troubeshooting this issue. I do not have .net studio, only dreamweaver and visual web developer. I have tried dotTrace, but I don't know what to look for or how to use this tool. Please help. thanks.

Try setting Trace="True" in the page directive. You can also use Trace.Warn statements to write out to the trace log.

I'm not sure how to use that. Do I just put that at the top of my page and that's it? How will I know where my problem is? Where can I find the trace log?

Try it out and see. Post back if you get any problems implementing it.

Ok, the big thing I noticed was:

Begin Load 0.00107373830440683 0.000019
End Load 100.018537963717 100.017464

I know that doesn't help, but I'm not sure what other part could be the problem.

Is there a limit on how many characters should be in a Session variable? Is there a thing as "too many"? I store a <ul> for our site navigation in a Session variable. Could that be a problem?

Oh, I remember now. I added trace warn statements throughout my code, but still waiting on a result...

ok, seems like the longest item now is our navigation, but it's not THAT long, and it doesn't tell me what's causing all these problems.

i think the problem may have been too large of a string stored in a session variable. I am doing this a different way and it seems to have helped my situation. Thanks for the advice on the trace, that really got me started on the path to resolution of this.
