My C# app very slow on Vista

[Katit]

Hi!

I installed my app on clients Vista machine. It's very slow when it
does database update and TCP messaging. I'm not sure which operation
slow.

Is there any know-how on what could be wrong? How would you approach
troubleshooting?

I can place some logging, this way I can figure what exactly slow. But
how I fix it then?

TIA

Don't worry about how until you know what. If possible, use a
profiler to identify the exact function that using so many CPU cycles.
You can then analyze it to figure out what the problem is.

before start running the profiler, have you tried this

Hello Charles,

Tried that - no help. It's slow on opening socket. "Slow" is like 3-4
seconds compare to less then a second on other PC's

Sorry, been out of the group for a while.

I'd start googling this issue, as it may be related to the IP stack
changes in Vista. You should also try to get a Vista test box and see
if you can replicate the problem there.
