Have another look at all my posts in this thread last night, you can see that -
1) My SPEED was NOT reduced - unless you consider a worst case 6.91Mbps out of 7.15Mbps profile maximum to be a problem.
|
It could be that the buffer and packet drops overall are not enough to drag your speed down. I think you'd see more of an impact on much fast line.

2) From the TBB Ping graph I wasn't losing ANY packets.
|
Before packets are dropped, they buffer. This will have introduced latency in things like ping tests / traceroutes. There was only a comparatively amount of packet drops (the most we saw was 0.27% of gold traffic, within a measurement period, through that device!) but the buffering impact would have been more substantial. You can see on your TBB graph a significant increase in latency at peak.

3) The ONLY measurable statistic that explains the sluggish performance were the PING times to UK servers.
4) Why were ping tests to foreign servers at normal figures, but doing pings to UK servers were awful ?.
|
That could suggest an upstream peering problem. I.e. a congested link upstream of us.

I don't dispute that the endpoint I was connected to might have been hitting a limit, but I don't think my posted figures show that.

I guess you are right, this doesn't necessary mean that your performance will be better tomorrow, but at least we can eliminate the capacity issue you ran into. We still appear to have something odd going on with the other guys on this thread and once we clear this, perhaps you'll fall into the same category. I hope not!
