    I'm going to try another switch will see if that improves or worsens the problem...

    Interesting thing is none of the screen shots are 100% of what Link say we should get even the 100mb lines are off by a factor of 8%

    Back up cisco switch in place, and a similar issue,

    Proxy not at fault as this is pointed directly to BGFL's load balancer
    Nothing is connected to switch so no load on the connection
    Similar issues at two neighbouring sites so could be exchange issue but schools further afield have reported problems.

    banging my head off the switch cabinet at this moment in time.

    I agree with all the above comments - we're not getting the advertised speed and I've raised this issue already. I suggest you all do the same. I agree also the overheads lost are at least 10% in most tests. This is possibly a combination of the filtering algorithms, the shiny new firewall, old proxies and an aging infrastructure (i.e. the Cisco switches) which together are all contributory.

    What I can't explain, is when using BGfL's Mini Speed test, it's always higher than when testing via speedtest.net It doesn't make any sense at all.

    Is that test to a box within their network?

    It's testing to the BGFL.EU server which is within the core of the bgfl and can't be reached from the outside

    I suppose (thinking about it) if the BGfL Mini Speed test is within the Intranet, it doesn't go through any firewall or filtering, just half a dozen switches reaching the server and back.

    You could argue it's pointless hosting one internally and it's not a true reflection of real life situations. The reality is 95% of requests are made externally, not internally. It does backup my theory though that we're essentially losing 10% of internet bandwidth due to the way the BGfL is setup.

    ahem.... if anyone gets lower than this I'll buy them a pint


    Untitled3.jpg

    Tested today at 14:30 direct connection to the switch, which we tested this morning at another site and was working fine, proxy is fine, nothing is downloading and the wifi is off so in theory nothing should be using the internet....

    So why is it this slow?....

    What is causing it to drop by 95 % I've checked every component and switch we have swapped them with like for like and still got the same. What else could it be?

    Photoshop here I come Would love an Edupint right now!

    If you want a 100% accurate reading, plug in a notebook directly into your gateway switch, normally port 24, with proxy on port 11 and panda on port 1.

    Try both the local speed test and speedtest.net. Guaranteed you'll get different results within minutes of each other!

    As to what's causing it - it's a combination of things, but mainly it's a BGfL load issue (I'm speculating), rather than your actual link or cable being the issue.

    This was done straight into the gateway switch at port 24,

    both local and speedtest.net give low results

    but it's been pants all day

    fed up tired and in need of a drink :-s

    No answer or response from link either.

    No one but me in the building only the DC and sims.net switched on and the internet drops from 7.2mbps at 8:00 to that at 9:00am Trying to update my servers today but may just give up and go home if this continues.

    Six days to go to the managers meeting. I hope this all settles down before then or the agenda may go out of the window.
