Networking Issues

[pulse8]

My network was working fine previously, but something has changed and I can't figure out what it is.

I used to get between 40MB and 50MB a second in transfers from my server, but now it just tops out at 14.6MB a second.

This is what my iperf looks like:

C:\>iperf -c htpc -l 1M -t 15 -i 3 -r

I think it's a software issue, but I can't find what would be causing this.

Anyone have any suggestions?

Thanks,
David

I figured it out. Apparently Steam is limiting my downloads to 115mb when it's running. Not sure why.

typical valve...probobly a new "feature" in one of their many patches.

Yeah, I don't know what they did, but they severely screwed up the networking when Steam is loaded. I guess I'll just have to keep it closed unless I'm playing a game.
