Speed fluctuations on gateways

I have speed fluctuations on some gateways and not others, can anybody explain this ?
I've dropped 2 hourly graphs below, one of the last 30 days and another of the previous 6 Months, On the 30 day graph you can see the gateway I was on for the last 20 or so days which seems to fluctuate at all times of the day, but if you look at the 6 month graph you will see multiple gateway changes, some of which are showing notable speed fluctuations while others are less erratic.

Yup. I've just bounced my connection and now I'm on pcl-ag07 I'm getting better speeds. I reckon pcl-bng04 must have some kind of issue.

Definitely something going on that is not SVLAN related in my opinion, plusnet been silent on it tho, only checking svlan's or blaming lines.

Yeah, mine has dropped back - single threaded mode anyway. It seems that multi-threaded download doesn't suffer and I wonder if that's related to the PN QoS? I'm speculating here but I wonder if it's treating each thread as an 'application' and is imposing a per-application throttle due to congestion?

Re: Speed fluctuations on gateways

It is not just for fibre, if not on a BNG gateway I get 4.7mbit, if on a BNG gateway I get 5.2ishmbit.  The down side is, I tend to get streaming issues with TwitchTV on the BNG's.

Re: Speed fluctuations on gateways

I have been noticing differences in ping and throughput consistency depending on the gateway I am connected to.
Sometimes a margin of an additional 5 ms in ping found by just changing gateway. 
Also I sometimes get peak time buffering when streaming via I player or netflix depending on which gateway I am on.
Is there perhaps a load balancing issue with these systems?

Re: Speed fluctuations on gateways

Is there any pattern to which gateways are performing better / worse?

And now back to the bng gateway again shows the return of speed fluctuations of around 3mb, I'm not seeing any streaming issue at present on any gateway Gus, then again my exchange has recently had some upgrades on 13/01/15

Re: Speed fluctuations on gateways

Well I'm not really sure of why there are these apparent differences but it was checked by Plusnet last week and no known issues identified.

Re: Speed fluctuations on gateways

I was just going to re-iterate that end to end checks have been done and that no issue has been found. Of course we'll look at individual cases via the usual methods.

Throughput and latency has been good the past few days via the bng gateway.  Smiley
