How to make sure you server NIC performance is at best on Windows?
- by Bobb
I realised that I followed some obscure paper on setting NICs on Windows for too long. It might be outdated with new hardware released in past couple of years and with W2008R2.
I read a bit about offloading and RSS settings on Windows and I realiased that it is very much circumstantial. Noone can really say - enable that and disable this. etc.
So what I really want is for my next server try and setup testing environment and measure how my particular application will behave with different settings.
The target is going to be latency of TCP primarily. Please note I am talking about latency inside the box.
Are there precision tools for Windows to measure latency (down to microseconds)?
P.S. I know this is not easy question. Windows time drift is awful problem for any precision test but still I am sure I am not the fist person to need that... Please share your experience
