RE: Finding Bottlenecks

Hi Nick,

Regarding on such issue, for locating the bottle neck, it is quite common
to do some tracing or profiling work upon your web application. for tracing
, the ASP.NET has already provided trace functionality:

#ASP.NET Trace
http://msdn.microsoft.com/en-us/library/y13fw6we(VS.71).aspx

#Tracing in ASP.NET 2.0
http://www.beansoftware.com/ASP.NET-Tutorials/Tracing-ASP.NET.aspx

You can add trace print statement in those page events/functions where you
put code logic(may block the page) so that in the trace output, you can
view the time point those event arrive and the next one starts.

Also, visual studio has provided good profiling tools that can help track
the performance issues:

#Analyzing Application Performance using Profiling Tools
http://msdn.microsoft.com/en-us/library/z9z62c29.aspx

#How to: Create Performance Session for ASP.NET Applications
http://msdn.microsoft.com/en-us/library/2s0xxa1d(VS.80).aspx

the profiling report can give you some info such as what are the most used
functions, or the most long run functions...

Hi there,

I have a website that functions fine locally, but when published to
the
server it develops a bottleneck during loading some of the pages.
Basically
what happens is the page loads to about 25% then it freezes for anything
from 10 - 40 seconds, before suddenly loading the rest of the page.

Of course I understand that this could be down to some code on the
page
locking the thread or suchlike, but I would like to be able to be able to
find exactly where the bottle neck is occuring. Strangely enough this
doesn't seem to occur in Firefox although Firefox displays quicker it
seems
to do whatever is holding IE up in the background so you get the illusion
of
it loading quicker.

Any suggestions on tools or methods for finding bottlenecks in page
loading? Many thanks in advance for your time and help.

Nick.
