Re: Q regarding channel ID, power and speeds

My best ever results currently are from Lancaster (as per my sig), and all the Paris ones - in fact all the France ones came out better than most of the UK ones.

Paris gave me 115-138 down and 75-127 up, which in itself is quite variable but I only did two tests. Massy was actually better - 210 down, 226 up. There seem to be two "classes" of speedtest servers - dunno if it's related to them using different IP settings (e.g. large windows), but they either give me ~20-40mbps upload results or 150+ with nothing in-between.

In fact, on some platforms (Win7x64) running the same test to the same server in IE could give me 200mbps upload but in Firefox only 40mbps, yet the same downstream result. Odd!

In case anyone's interested I decided to speedtest all* of speedtest.net's servers.

Spoiler: 


*By "all" I don't actually mean all. I'm adopting VM's fairly loose interpretation of "all", "everyone" and "unlimited". I actually just did the UK, Ireland, France, Belgium, Netherlands, Denmark and Luxembourg.

The results are below. They should really be taken as an sorted list, rather than absolute quality ratings.

I only did one test on most of them, under one condition at one time. Conditions may not reflect any particular situation on the VM network It gives us an idea of the relative speed capabilities of each server. The "Yes/No" columns are based solely on my opinion of their suitability for testing each tier.

Code:
Group 1 - Superfast uploads - Great if you have a symmetric line, fibre, etc.
Apart from a few with consistency issues, they're all good for 100mb+

I'd be careful if you have 10mbps+ UL Infinity or other FTTx

Group 3 - Epic fail servers. Crap at just about everything.
Probably best avoided for anything until they'e fixed.

Derry           NI       28.8   23.6   25   FAIL      FAIL       FAIL
Some day I might get round to doing automated tests (e.g. 10+ per server) and working out some standard deviations to estimate stability. But not till I get my own connection stable.

Curious. I hit about 40% on my dual-core i7 (laptop) but only at 300mbps+. Given that an older 3Ghz Core 2 Duo has no issues exceeding 500mbps+ on Speedtest.net, I wouldn't say CPU is an issue.
