How does a card hog CPU ? My task manager only shows processes using CPU. If there is a process talking to the card and it's using a lot of CPU, you could lower its priority if you think it won't have adverse affect. | |||||||||||||

For the rest of us, the best you can do is pick a card which does not hog the CPU. Generally, the fastest cards do more work right on the NIC so there is less for the CPU to do. Which card/OS/system are you having trouble with? -- Basic Bob gbasigcbobg@gatt.gnet the g's are silent | |||||||||||||

We had cards years ago that were called smart cards that did much of the TCP/IP work on the card (which had its own CPU and was downloaded with firmware on system startup). Today's CPUs are so fast that I wouldn't even bother paying the extra bucks for a smart card (we were running like 286's back in those days and it made sense at the time). I would think 3Com would have smart cards and you probably pay at least quadruple for them since a reg card is like $10-20. They'll offer remote management, processing offload features and the like. The NIC shouldn't be hogging the CPU unless you either have negligible CPU or extremely high network traffic. I would check both first. See what the CPU is like with the network disabled and see how much traffic you have with the net enabled and a monitoring tool checking the traffic load. You can get a little info from the Task Manager Networking tab (on XP and the like for example). I seldom go over 1% network utilization unless downloading which still stays under 10% since it's WB (not local LAN). | |||||||||||||
