Unbearably slow downloads on only Arch.

I run several computers in my apartment, and every one has been getting a 3Megabit minimum connection on uncapped downloads... however since installing Arch, I can barely get 50k out of downloads. Websites seem to load just as quick as ever, but FTP and HTTP transfers of any large files take an extremely long time, occasionally jumping up to 100k for a couple seconds, only to simmer back down to 20-50k. Right now a supposedly 10Mbit FTP connection, via my 5Mbit CDSL is downloading at 13.5k/s.

This only seems to happen with internet transfers as well, I can easilly get 3Mbit connections to my NAS servers and other PCs.

Re: Unbearably slow downloads on only Arch.

Archlinux package downloads are throttled to limit the download speeds.

Sounds like TCP window scaling - disable it. Also see that page re IPV6.

To clarify, ftp://ftp.archlinux.org is throttled.

Still having this problem. After disabling TCP window scaling, and trying that other option under the same section, speed has increased very slightly. It's still taking a long time to load most web pages.

Ftp transfers start out at 2-10kbps, but go up to nominal speed after a few seconds, however.

Re: Unbearably slow downloads on only Arch.

Are you using linux on any of the other systems? I'd be interested to know if you've tried another distro on the troubled system to see if it's an Arch issue or a more general linux issue.

Yes, I have OpenSuSE and Mandriva on 2 of the other computers. I've also had Ubuntu on this one (but I really can't consider that linux, haha). However the problem seems to have gone away sometime during my tinkering last night.
