Is it possible to give ports a processing priority?

Hi,

I have written a simple internet client/server app in VB6.
It normally works fine until the server PC is also downloading stuff from the internet, then it slows down.
Is there a windows API (XP) which will allow me to give a port a higher priority than others?
Is there an XP setting to do this?
Any ideas/help/comments would be greatly appreciated.

Thanks

Short answer: no.

You cannot directly control bandwidth usage of another app with your program as far as I know.

There may be something to tweak bandwidth usage in the registry but that would effect all programs including your own.

Thanks DigiRev,
I was afraid of that.
