Hi,
I've noticed that on my network I have latency spikes and after some research it would appear that I have them because I have a FreeBSD based OS, I use a Intel NIC with an IGB driver, and a PPPOE connection. I've added some tunables which in testing appeared to have cured the spikes - I was seeing like >500ms (some as high as 2000ms if memory serves me well).
When there isn't much activity on my network, i.e. I am the only one home and not streaming or anything, I can ping 8.8.8.8 and get on average say 12ms over 10 requests (I've tested up to 250 at one second intervals) and it's quite consistent now. However, if I ping somewhere and then start streaming, the pings appear consistent with no spikes but are higher at 40ms on average over 25 requests. An obvious improvement, however is this normal, or acceptable on a BT based line, 15/62Mbits for it to jump by around 107%? Would you expect response closer to normal but a little higher maybe? Probably a stupid question.
Additional info: I do have VLANs and have set the priority on each, most at default but my Work vlan has the highest over all the others. The device that I started the stream on has a lower priority than the computer doing the pinging on the Work vlan.
I have bought another NIC but a Broadcom based one as it's cheap and it's probably good to have a spare, I will test it and remove the tunables when I receive it.
Thanks
