Packet Loss jumping erractic
« on: July 16, 2011, 09:00:49 am »
I recently noticed last night on my new snapshot dated the 15/07/11

my packet loss is going above 30% causing the internet to be slow.

i have further investigated this and it seems something related to my bittorent traffic. when the bittorrent on my freenas drive downloads. the packet loss goes up and ping increase from 15ms to over 300ms

I am confused as to what is causing this

I dont have traffic shaper enabled

You're likely maxing out your upstream and/or downstream bandwidth, which will cause loss and jitter, just a fact of networking. 50% loss is excessive but not uncommon with residential ISPs as they tend to really start dropping your traffic once you start hitting P2P even before you hit your bandwidth limits.
