I've been experiencing slow transfer speeds on my server for quite some time now and I have no clue what is causing it (or how to further debug the problem). Transfer speeds both download and upload are both very slow at around ~50kb/s.
I've ran some wget tests, and found that transfer speeds to other servers within the datacenter are normal. The slow speeds only occur from transfers going in and out of the DC. I've tried disabling firewalls, tweaking the TCP window sizes and the slow speeds still occur.
So, any thing I can do to help further debug this issue to find out whether it is a network issue, something on my box etc?
Any input greatly appreciated
