Anyway, thanks for your reply, and I'll hazzard a direct question.
If am pinging my default gateway, what sort of numbers would you call "good" or "normal"?
typically, I get below 20ms and when the system seems to be running optimally, I'm getting close to 10ms (and sometimes under)
There are times when the pings go all over the place, (eg spikes into the many hundreds;thousands or even a complete timeout)
What would you associate that with? ie. is this a manifestation of ARP flooding or something else (eg congestion)
But I'll understand if you feel you can't be specific or even answer the questions.
It can vary depending on the OS you have (not windows if you're seeing 20ms to the gateway :) ) anything over ~60ms and there's probably "a network event" occuring that we're usually pretty quick to find and fix.
