I've just swapped my old SH1 for a Hub3, on the 50Mbs service.
It's very early days, but yesterday evening I was getting significantly better download speeds than I have done in peak time for a long time (I'm affected by contention ticket F003508185).
D/L speed just now (Sunday morning) is testing consistently at > 35Mbs, BUT I am presently getting painfully slow browsing. You know what I mean when I say I get time to read in the status bar the URL of every darned little element of every darned page
I thought this would be a DNS issue, but it seems exactly the same with default, Google, or OpenDNS server addresses set.
Any ideas? I haven't changed any default settings in the Hub3; The SH1 died altogether incidentally, so I can't go back to compare settings.
This may be a complete coincidence of course, but in any case any thoughts on how to diagnose/resolve would be greatly appreciated.
I have done a few traceroutes which are not suggesting high latency - e.g. to Google below, but it will be interesting to monitor more thoroughly.

Overutilised areas should have perhaps a small increase at peak times with a slope leading up and a slope leading down. Cliff-edge increases and drops indicate a problem in the core network rather than a local overutilisation one. Those really shouldn't happen.
Thanks for that - certainly could be, although I don't seem to be seeing anything like the latency spikes that folks are posting in that thread, and (in quiet times) outbound pings and tracerts look fine, when the browsing is slow.
Funny thing is that, for me, the SH3 has certainly improved the overall experience a lot (especially streaming TV), over an SH1, in an area known to be hit hard by over-utilisation.
As it happens I do have an SH2ac, currently used as a secondary router, but not sure I can be bothered to see whether getting it activated is worthwhile. It would be very sad if it makes things worse again!
