I moved to Fibre with Pulse8 in November 2016 and had single thread speed problems almost immediately. After some lobbying by Adam at Pulse8 with TTB, the root cause was eventually identified and I had a period of pretty solid single thread speeds.
This deteriorated with the advent of the non-Flash based TTB tester in May this year, which I eventually traced down to my AV, Eset Cyber Security Pro, impacting the single thread results. this was rectified by swapping to KIS which appears to have a negligible effect on the speed test.
For most of the rest of my time with Pulse8, the single thread speeds were fairly solid although there was always a slight undercurrent of poorer results. After 12 months I decided to migrate to Aquiss. The result was very good single thread speeds out of the working day, but their business prioritisation and/or the Entanet node I was connected to running a bit hot, resulted in very variable results throughout the day.
Martin Pitt at Aquiss very graciously made the offer for me to migrate away without penalty and in mid-December I migrated to IDNet on their Fluid Data TTB backhaul.
Since then speeds have been quite variable without their being any obvious pattern to it. Out of 5 consecutive tests I might get one really good one, one poor one and three middling ones regardless of when in the day I am testing.
I attach a scatter chart for the last three months of my TTB tests.
In general terms the IDNet connection is giving me worse single thread results than either Aquiss or Pulse8 (see figures below).
IDNet Aquiss Pulse8 Mean 59.7 60.8 64.2 Median 63.6 69.5 66.9 |
As the distribution is somewhat skewed the median figures are probably more significant than the mean.
I reliably sync at 80/20 with a 9dB margin and my connection passes the normal line tests that ISPs do (as confirmed by both Aquiss and IDNet).
My MDWS results are available under jaydub and seem fairly unremarkable although my Quiet Line graph is noisier than ideal.
I am in discussions with IDNet about where to go from here, but would welcome your thoughts.
A few questions from my end:
- Do most people's TBB results have the single thread result coincident with the multi thread test?
- Is cabinet congestion a possible cause of the single thread degradation, bearing in mind that that the results are pretty much consistent whatever time I test?
- Is what I am seeing just a factor of my line and unless the line worsens sufficiently for there to be a fault condition, there is very little that can be done about it?
- IDNet are offering to move the backhaul service from TTB. Is there any reason not to go ahead with this?
