ASP.NET Application Performance Issue

[ik646]

Good Day, All.

My company has recently developed a ASP.NET application and have begun migrating my local users to the system. Since then, there has been a considerable increase in our WAN utilization. I am trying to analyze the change, and my sniffer shows 'minor' errors on ACK To Long and Window Frozen for clients' transactions with the web application. Are these really minor, or are they indicative of application performance problems?

Thanks.

There's no way most of us can help you based on that little information. I think if you show some code of suspicious files, we could help.

Here are a couple things that come to mind when I think of performance hits:

Using old ASP code
Not using efficient queries, ie pulling a thousand records out of the database and filtering it client side. Avoid pulling them out in the first place!
Not closing connections to data.
Using datasets instead of datareaders
Not paging data
Using xml as a datastore for lots of data

Quite a few other things but those are what come to mind. Post some of your source code and we can look at it.
