Hello
Does W2003 sp1 provides counters to measure the perfomance of the windows firewall?
or is there a way to monitor the cpu consuption of the firewall / ics service?

cycles per byte or cycles per operation:
(NumProc * ProcSpeed * CPU Utilization) / throuput
throughput can be requests per second or operations per second. this is where cycles/byte or cycles/op is derived from. you can use many tests to test the througput here, but one of my favorites is simulating a webload, thereby measuring requests/sec through IIS.

What exactly are you looking to measure in regards to the performance of the firewall?
CPU consumption of the firewall is negligible. It's the filters that are put in place that degrade network performance, causing CPU time to be spent checking these policies to ensure incoming/outgoing requests are legit. When the filters aren't in place, more time can be spent towards handling incoming/outgoing requests. The only way to truly measure the amount of degredation is to measure the cycles/byte with and without ICS running. ICS running by itself does very little in terms of consumption.
