Bandwidth test
09-16-2010, 09:22 PM
Good evening,


If I've read your feedback correctly (over 250), above 100Mbps (12Mb/sec) the results are similar to 5% i.e.: with ADSL, 100Mbps servers and across Europe.

Next, if you have a server 1Gbps/10Gbps in France or Europe, it depends. The direct-proof is faster, as the a10-proof is faster. I think it depends on where the traffic is drawn and the distance in kilometers between the IPs. Packet fragmentation with MTU 1500/9216 done with the ACKs take some time to arrive. And this will slow the flow. But may also be the fact that we did not disable the MPLS between Roubaix / Paris that plays on too. In any case it's very interesting and there are many things to understand and improve in absolute terms but also in setting up load balancer as a10. I have not activated the internal cache on the router to force the transfer between the infrastructure, but we can further optimise flows.

Thank you all.

If you have 12 minutes ...

Good evening,
If you have 12 minutes could you please test the 2 downloads on then the same download on then send them to me on
Your verdict: it's the same thing or there's a difference?

Long version:

We will use this test to announce a new router for load balancing. This is a a10 load balancer brand connected in 10G to Paris. it's connecting to on the a10 you are "redirected/load balanced" on which is found in.....Roubaix.

Why do this? To test the performances. In theory it should have the same performance as that of the proof server either directly or before with the a10 . But is this right? Is it stable?

We're thinking of using this new router for Cloud Computing at the dC load balancing level but not only just this. It can translate IPv6 to IPv4 and so if you have a working site, without changing anything, in less than 5 minutes anywhere in the world, you can start your site in IPv6 ... the SSL hardware, hard gzip compression etc. etc.... In short, there is what we're hoping for ... but well before that we must validate the tests ...

Thanks for your help.

All the best

It's been a while since we have been asked to set up a server specifically for testing bandwidth. Eg.: to download files and
see the quality of bandwidth together with the broad band.

It's done:

The server is a 10G HG connected to our network from a HG like a HG standard.

All the best
