OT: bit of internet speed research help please

[John Rumm]

Could some of you do a quick experiment for me?

For windows bods (I will assume the *nix guys can work this out for themselves ;-), open a command prompt and type:

ping

-t

and hit return. That should start it spewing out results similar to:

Now open a web browser and visit a page that is large and hideously graphic intensive such as:

(if you have been there before, clear your browser cache first for the full effect, and note that page will rot your brain if you read it!)

You will probably see the ping times increase while the page is downloading. Could you cut'n'paste a log of the pings with a bit of before and after. Also a rough note of your sync speed, and broadband technology (i.e. ADSL, cable etc).

(hit CTRL+C to stop the pings)

Ta muchly.

(The reason for asking is I could do with some other results to help "educate" a clients supplier! I was having a conversation with one of their tech support bods the other day. They provide an online web based service to the client, which seems to crap out on them from time to time. The suppliers (as usual) were blaming the clients internet connection[1].

To justify this claim, he produced a log of ping times to their server, and highlighted that at some points, the response was over 200ms (highlighted in red with lots of exclamation marks ;-)

I mentioned that he was testing the response on a shared connection, while potentially ten other PCs were using it, and while he was also running remote control of the PC he was using for the test - so he should expect ping times to rise as the load increases, since its a "best effort" protocol.

(i.e. With a thinly veiled, but as yet unvoiced assertion that if your software falls over when you get a couple of tenths of a second unexpected delay in response times, the protocol you have designed is not appropriate for the task!)

[1] There may well be problems with the connectivity, but speed is not one of them! A pair of load balanced ADSL2+ connections about 300m from the cabinet - each synced at >22Mb/sec!)

There you go. Cable internet, (Virgin Media). Can't remember the quoted speed, but speedtest.net just ran a comfortable 20M, which seems possible. As you can see ping is stable at 17-18ms until I load the page, then settles back.

On an ADSL2+ circuit the rarely syncs above 2mbps, ISP is plusnet.

[Andy Burns]

Jeez, that takes a big hit, what ISP and what connection speed do you get?

[Andrew Gabriel]

ISP: Andrews+Arnold Link: ADSL2+, syncing at 20.8M

Tell them 200mS ping is nothing. 2000 might be cause for concern.

hmm wonder what the office connection shows. That's IIRC a

10meg leased line, though IT were muttering about an upgrade... 12mS. And no effect from the page load.

Can you get stats for corrected/uncorrectable ATM cells out of your router?

[John Rumm]

You can get a fair amount out of it - certainly CRC error rates etc. Not sure if you can get a count of corrected ATM errors though.
