Outbound connection bandwith throttling

[hockeychap]

Morning all,

Question for one and all - am experiencing some peculiar network characteristics which look like a throttle on outbound connections.

I've just had some users report that VPS has only been distributing files at ~10Mbps rather than the 100Mbps. I've now tested this and got the same results.

In order to test this I have set up a 13MB file on both machines available to both ftp and http access. The results (an average or 3 runs) are shown below:

Method | Hosted Machine | Fetching Machine | Average Speed Achieved | Best Speed |
FTP get | 1&1 VPS server | 115.124.110.xx | 2.8MB/s | 7MB/s |
HTTP get |1&1 VPS server | 115.124.110.xx | 3.8MB/s | 6.8MB/s |

FTP get | 115.124.110.xx | 1&1 VPS server | 650 KB/s | 1.2MB/s |
HTTP get | 115.124.110.xx | 1&1 VPS server | 670 MB/s | 1.2MB/s |

Given that when grabbing files from a remote machine I get towards 10MB/s, but when supplying file I get no man 1.2MB/s (about 10Mbps), I can't see that it's anything else other than a throttle. I've also checked iptables, tc and mod_bandwidth.

I've raised a rather urgent support ticket, but does anyone else have any ideas where else I could check ?

Cheers
Justin

It would be great if you can let me know the ticket ID and also mention the file that you are testing. We will look into this and the ticket will be updated shortly. Moreover we provide with a 100Mbps line, you can use the traceroute from your server to check the speed.

Rachael,

The support ticket is #KOX-818-32579 which should now be closed as the issue is resolved. It appears that the network interface outside the VPS needed to be reset and the server rebooted.

Just one of those things I guess, but thanks for the prompt service (took about 1 day all in to work out where the issue was exactly and get the right log files of both the VPS and the 1&1 server that I was using to test).

Best wishes,
Justin
