PLEASE LOOK! I need to test something!

Dr. Z · 18-10-2007, 22:08

I need to know the realistic maximum upstream I can get from my link, which means multiple phat pipes downloading stuff from my server! I should have 100Mbit up, but I don't think thats a realistic upload for the majority of the net because I don't think JANET have the best UK backbone links?

Please can you all go to http://146.87.15.17:1194 and download, preferably using something like FlashGet, one or two of the larger ISOs there? Once you have got a steady rate going, can you post here and let me know what ISP you are on and what sort of speeds you are getting?

Thanks a lot guys

Two tests using Ubuntu desktop - one is bouncing like a mad thing between 350-450KBps with an occasional 500KBps thrown in. The other is fairly stable at 600KBps.

PS - both are on fat pipes (we're talking 30MBps+ here - one being a fast business ISP and the other being a datacentre in Docklands).

Bouncing around 100-120KBps here, on an 8MB Plusnet connection.

Zirax · 18-10-2007, 22:35

Around 230-250k/sec on an Entanet 4mb connection. Note that this is probably the worst time as all the downloaders have just switched their boxes on with Entanet.

Dr. Z · 18-10-2007, 22:36

It seems that JANET must be busy but nobody is able to pull more than ~600kbps from the link no matter what (although I can pull stuff off through the firewall at ~5Mb/sec when I'm not going through JANET).

My traffic graphs show that I have about 1Mb/sec to play with for a reliable upload maximum, more if JANET pull their finger(s) out. Thats alright for a fair few listeners at ~96kbps

Zirax · 18-10-2007, 22:43

What about organising a brief blast with the people from bd. Say get everyone to listen in over shoutcast at X time? If its choppy we can let you know. 128kbps would sound better but you are limited in what you can do

Mark · 18-10-2007, 22:49

I should mention that I wasn't using FlashGet or any other similar tool. I'm not prepared to 'rape' the work connection, but if you know of anything that'll run on Gentoo then I'll happily install that in the DC.

CPU cycles more than bandwidth mate Encoding is done by a 300Mhz PII

We have an Ogg Vorbis stream for people that want quality but we only allow a handful of connections to that

I'll do a couple of tests today from work. I know a couple of boxes with gigabit interfaces direct onto our 10gig backbone.

From my box in the data centre, I'm bouncing around 800-900k. I usually see around 4 - 6 Mb/sec, but I'll see what happens from one of our main servers.

Edit:

Okay, from a box I know has a nice 1gig interface on it I'm seeing the same kinds of speeds, between 800k-900k/sec.

From what I can see from a traceroute I'm probably using a slightly different route to most folks here. Claranet has infrastructure in Telecity Manchester and a POP at a building part owned by Manchester Uni.. if I'm reading this right stuff traffic is going via our 10gig link to manchester and then direct into the manchester infrastructure, so I presume there is some peering there. Unfortunately the two critical points on the route don't have reverse DNS records so I've no idea what they are

. Starting at hop 7 in our manchester infrastructure:

7. g1-0-0-im1-cr1.router.uk.clara.net 0.0% 20 11.1 28.4 8.4 176.9 43.4
8. 195.102.254.66 0.0% 20 12.8 11.1 8.0 12.9 1.5
9. 195.102.254.118 5.0% 20 11.5 10.3 7.8 13.3 1.6
10. gw-man-kb.netnw.net.uk 0.0% 20 11.9 11.3 9.3 14.0 1.3
11. gw-man.netnw.net.uk 0.0% 20 12.1 11.4 8.7 13.1 1.3
12. ???
