So THATS it!
Mar. 26th, 2009 08:53 pmWhen I inherited the machine that is now being converted into my video/file server, I noticed that it had two separate ethernet cards. I asked at the time if it had been used for something fancy, but
pphaneuf said no, one of the cards was broken, so he just stuck another one in there.
A quick test showed both cards working fine, so I took one out and have been using the other ever since. Well, I just worked out that it is, indeed, 'broken'. It works perfectly well, but has a top speed of 1 Mb/sec on a 100 Mb/sec line, and that's with 100% CPU utilization. A quick Google shows that its a known problem with how this particular card reacts to the generic network driver that is the only Linux support it has.
So, I think I'm gonna swap out the card, put its replacement back in, and see what happens to performance.
