TCP/IP processor load under QPC2

If not everyone knows: QLirc (by Tim Swenson, enhanced by Dilwyn) is a program to chat via QLforum.
What I have found out (under WIN7 with QPC2 4.05, 2 proc PC) is, that it gives a processor load of 50%, even if QLirc does nothing. So the processor fan runs like a BAC 1-11 and kept me from sleeping
. When I quit QLirc, all is silent. So I think, it has something to do with the TCP/IP connection.
Has anyone an idea, what that could be?

Ah sorry, I read your mail but it's just too much at the moment. Looking at the code QWirc does busy waiting, which is always bad for CPU load. Try changing INKEY$(xx, 0) to "INKEY$(xx, 1)" to rate limit the loop to 50 accesses per second.

The current version of QLirc does this anyway in an attempt to reduce the load - I had suggested this to Ralf when he contacted me about it.
QLirc has come on a lot since Tim's early demo. It has been used to connect to the QL Forum IRC channel for several hours by a few people testing it.
I'm adding more and more to it, almost ready for a trial release now.

Ah ok, I googled it and just found Tim's version. Can't keep up with most of the forum right now.
Cheers, Marcel
