Hello everyone I'm back again to ask u a question (sorry )
I found that my conection on my Win box is definitely faster than the one on my linux box. So i found this cool site to test my LAN 10Mbit connection
site:http://miranda.ctd.anl.gov:7123/
and i ran the test...
I can't copy the results cuz ctrl-c doesn't work but it says:
Round trip time=221 msec Packet size=1368 Bytes No packet loss
This connection is receiver limited 81.87% of the time
Increasing current receive buffer (61 k) will improve performance
this connection is sender limited 6.16% of the time
Increasing current sender buffer (63 k) will improve performance
This connection is network limited 11.95% of the time
Selective Acknowledgement:ON
Nagle Algorithm: ON
Explicit Congestion Notification OFF
Time Stamping: ON
Windows Scaling: OFF

So i typed in console:
$:cat /proc/sys/net/ipv4/tcp_timestamp
1
$:cat /proc/sys/net/ipv4/tcp_window_scaling
1
$:cat /proc/sys/net/ipv4/tcp_sack
1
$:cat /proc/sys/net/core/rmem_default
65535
$:cat /proc/sys/net/core/rmem_max
65535
$:cat /proc/sys/net/core/wmem_default
65535
$:cat /proc/sys/net/core/wmem_max
65535
$:cat /proc/sys/net/ipv4/tcp_rmem
4096 87380 174760
$:cat /proc/sys/net/ipv4/tcp_wmem
4096 16384 131072
From what I know the last 2 are the memory reserved for TCP rcv buffers and memory reserved for TCP snd buffers so these are the ones i gotta change but how and how much??
then how I can Enable Windows Scaling?
My Win relevant setting are:
Tcp rcv windows = 513920
Max MTU = 1500
Window scaling: YES
Time Stamping : NO
Selective Acs : YES
Path MTU Discovery :YES
Black Hole detect.: NO
Max duplicate Aks : 1
TTL : 128
How can I have the same settings in Linux?
I'm sorry for the long post and hope you can help me.
Thx a lot in advance
