Seemingly it was a mistake , whilst PlusNet may claim everything is gold - at peak times Gold doesn't seem to apply to everything.
Usenet - (yep that old service!) is strongly shaped on PlusNet fibre more so than anything else (although I guess P2P is equally knobbled by PlusNet).
I have a 80/20 service and sync around full speed 77Mb ish, usenet is usually used outside of peak periods (10pm onwards or 9am - midday) and I get full line speed - its amazing 8MB/s+ downloads - excellent.
So imagine my surprise when about 6:30pm tonight I get speeds of 1.2MB/s from usenet... ran a speed test which shows 60Mb connection so a bit low - but not bad, restart usenet - 1.2MB/s still. So I try a 1Gb download file from this site - that downloads at 8Mb/s - but usenet still 1.2Mb/s. Hrrmmmm.........
Reboot router to change pipe
62Mb speed test
7.8MB/s 1 Gig file download
Something seriously wrong here - so start logging pipes and speeds.
Speed test = 60/16
1Gb test file = 8.03MB/s
Usenet = 2.93MB/s
Speed test = 53/16
1Gb test file = 7.22MB/s
Usenet = 1.14MB/s
Speed test = 63/18
1Gb test file = 7.61MB/s
Usenet = 1.78MB/s
1Gb file = 7.54MB/s
Usenet = 1.43MB/s
Usenet = 1.41MB/s
I think its fair to say its not exchange contention as speed tests are good, and other file downloads are good.
I think it has to be usenet traffic shaping taking affect making speeds so low when compared to other downloads, the question is why? If everything is Gold - then why is usenet affected and other services are not affected?
Thoughts from others would be most useful. - but this is clearly not what PlusNet have said would happen on their unlimited service.
FWIW - the best gateway was PCL-AG06 which was an average of 4.10MB/s
