Hello

answering to myself:

found that doing a net.inet.tcp.rf1323=0 have multiplied my speed by ten

net.inet.tcp.rf1323=1 download at 120K/s
net.inet.tcp.rf1323=0 download at 1.5M/s

i have tried to adjust windows size, but default value are good.

I still need help to reach a 5M/s rate which is good enough on a 100MbFdx link

RFC 1323 extensions shouldn't be able to cause that kind of effect.
I'd be suspicious that there's a duplex mismatch on the link; 
are you getting a lot of collisions?

slow download, quick upload

2005-05-24 Thread User Patrice 
Hello

I m running freebsd 5.3
the freebsd is connected to 2 PC in a DMZ.
Upload and download from both PC are OK
but when the freebsd try to download a file from a PC, it is slow.
The speed is around 5M bytes/s when the DMZ download a file from DMZ or from fre
The speed is around 120K Bytes/s when the freeb download a file from DMZ

i did some tcpdump :

servidea.dvp.idea is the freebe, savdvp6 is in DMZ

tcpdump host servidea and savdvp6 (the slow download from DMZ) :
(wget http://savdvp6/a.bin)
