Sluggish performances with Linux

2004-05-20 Thread Laurent Goujon 
Hi all,

Currently I have a two computers : 
- The first one is my gateway. It's running Freebsd 5.2 stable, has two
networks cards, a realtek 8139 and a broadcom 4401
- The second one is my laptop and it's running most of the time Linux
(Mandrake cooker with a 2.6 kernel), sometimes winxp (because of the
lack of support for some hardware components) and has a sis900 network
adapter

My problem is :
I have very poor performances with tcp streams from my server to my
laptop (0.35 Mb/s), but throughput is normal from the laptop to the
server (90Mb/s) and also (my favorite one) from Internet to my laptop
(~4Mb/s).
When I'm running WinXP, all is quite normal.

I've tried to invert network cards on my server, to bypass my switch :
no result

Any idea ?

 Hi there
 If server to winXP works perfectely, look no further
 the prblem is the host not the nics or server, so
 check the linux conf. sorry no help there

I'm not sure about that because on one side, incoming traffic from
internet which pass thru the server has a better thoughput than the
local traffic, and on the other side, when I replace FreeBSD by a linux
distribution, I have far better performances. Which kind of parameters
could have an effect on this impact ?
