Seeing reduced single thread performance on Uno (TTB)

Anyone else on TTB seeing reduced throughput on single threads as per the above test?

It's not really peak time at the minute (11:16pm at time of testing) but these are my results:

Fibre+ Pro (TTB) line with a sync of 80/20. The reduced speeds are from a pretty heavy fq_codel implementation which I need to tweak.

Cheers for that, I notice single thread is slightly slower but not by much. Here's mine again.

My Single thread speed is exactly half of sync speed.

Well my single thread download speed problems seem to have been fixed.

Dunno if Talk Talk have done something or it was me re-applying windows anniversary update which has created new network adapters maybe RWIN has changed with the update.

With a line as straight as that on your single thread speed it definitely looks like some sort of hardware is enforcing a limit because if it was congestion, I would have expected the throughput to be fluctuating around more.

I am on TTB with TTB directly - I have also had a cleanup on my single thread issue.

That's why I chose TTB as a supplier no one round here has heard of them thus little congestion hopefully. The hardware limit is my modem sync with a dodgy underground feed of non twisted pair which I am hoping to get replaced.

... With this logging we've identified that circuits connecting over tunnels on 'odd' IPs are fast, whilst those on tunnels on 'even' IPs are slow.

We have been testing the Telehouse interconnect this evening with TalkTalk engineers. This involved a ~80 minute conference call and setting up a very simple test of a server our side plugged in to the switch which is connected to our 10G interconnect, and running iperf3 tests against a laptop on the TalkTalk side.

The test has highlighted a problem at the TalkTalk end with the connection between two of their switches. When plugged in to the second switch we got about 300Mbit/s, but when their laptop was in the switch directly connected to our interconnect we got near full speed or around 900Mb/s.

This has hopefully given them a big clue and they will now involve the switch vendor for further investigations.

TalkTalk have just called us back and have asked us to retest speeds on broadband circuits. We're moving traffic over to the Telehouse interconnect and will test....

23 Mar 23:07:31 Initial reports show that speeds are back to normal!

I am not sure if it was Talk Talk Biz. or a local problem with RWIN.

Interesting that http://www.thinkbroadband.com/speedtest/results.html... doesn't show your ISP. Whereas http://www.thinkbroadband.com/speedtest/results.html... does.

On speedtest.net it comes up as Xilo. It is interesting I always fill in the ISP box, sometimes it shows sometimes it doesn't. My sig has the latest one.

Xilo and Uno IP blocks are mighty confusing
