Hi,

We have a web app that was written in .net 1.1

We recently converted the app to run in .net 3.5 and put it live.

The application is running on 3 Server cluster and the servers are
pretty heavy duty.

Does anybody have any ideas as to why the application is so much
slower now on 3.5 than it was on 1.1?

No clue, but I would guess you are using some deprecated features or the
code is not properly architected .NET code.

If deprecated, you can search the docs, find the code and use more
"modern" techniques.

If improper architecture, you will have to cull through the code and fix
the architecture through refactoring.

The best bet is to add tracing and find the routines that are causing
the slow down.

One other thing that could affect things is the configuration of the
server. This can be site config or machine config. This is a harder
route to go down, so I would trace the code first and find the
bottlenecks.
