I have been using slackware for 2 years now, now I'm on slack 10.
First about network. At home I have LAN with two computers, then a router (which is a gateway and DHCP), which is connected
to my ISP's LAN, in which there is my hosting server located.
I also have windows xp, which is left after my colleague on my pc.
Now when I want to upload to this hosting server my speed is ~5kB/s in Linux, but in windos it's ~500kB/s, 100 times faster. I tried alot of configs, and have done voodoo for past couple of days, nothing seem to help me increase upload speed under linux. There is another thing. When I turn on DMZ on router for my computer, my download speed goes twice as small, from ~1MB/s to ~0.5MB/s, that's in Linux. In windos however, turning DMZ on and off doesn't seem to affect the speed at all . My router is unknown and probably was bought somewhere for very cheap, it's adapter says D-Link, but nowhere else there is anything, only serial number, but no name of model or name of company. It amazed me, that all that time that I have been suffering uploading those files, it was actually some configuration problem.

Please give me an idea, maybe it's something with firewall or routing or something?? Where to look?

try ping or "ping -f " (flood)

PING ******.com (***.***.***.***) 56(84) bytes of data.

--- ******.com ping statistics ---
1791 packets transmitted, 1791 received, 0% packet loss, time 24305ms
rtt min/avg/max/mdev = 2.984/4.039/8.525/0.758 ms, ipg/ewma 13.578/3.737 ms

I forgot to say that I download with ~1MB/s from this site, but upload is very bad, and to everywhere, but to this site it shouldn't be, because there are no traffic shapers between my computer and the server. Besides, it uploads well under windos. So I have something in my config that makes upload 100 times slower, and I can't understand what could it be. (I also can't do traceroute to anywhere if that's of any clue. Even with DMZ turned on.)

was earlier Slack ok ?
