[LARTC] Slow download speed with windows/linux combination.

[LARTC] Slow download speed with windows/linux combination.

[Carlo Wood]

Hiya,

I am having a weird problem.  I hope someone here
can help me with it.

My setup is as follows:

internet --- cablemodem --- linux firewall --- linux box (with vmware)

I always used to have a download speed of 150 kb/s, until
at one moment I got a new cable modem from my ISP (connected
to a different platform), from that moment on I suddenly got
a download speed of around 10 kb/s.  After a month, they
changed something perhaps - because recently I got a download
speed of 100 kb/s, but never at the full speed anymore.

However - recently I installed windows 98 on vmware on my linux
box, and to my suprise I get 150 kb/s download speeds there!
Apparently there is a difference between windows and linux that
causes TCP/IP to work better with windows (with my ISP).

At the same time however, when I try to download from
download.microsoft.com I get an EXTREME slow "download" speed,
like 100 b/s.  This is NOT a problem of congestion or
something - a neighbour with windows XP (and no linux firewall
or anything) got 150 kb/s from download.microsoft.com at
the very same time.  So, also here this slow download speed
must be the result of me using a linux firewall and/or
vmware on a linux box.  Again: I DO get 150 kb/s with that
very same setup when downloading from test.arnhem.upc.nl,
so the problem must be with download.microsoft.com in
combination with that I am using a linux firewall or something.

I am wondering if these are known issues; what could be
the problem here?  What is linux doing that is making
download.microsoft.com "refuse" to serve me?  Why is my
download speed when downloading with linux slower than
when I use windows 98 (on vmware/linux)?  These things
highly confuse me.

Can someone shine a light on this?
