This is a good question. Windows machines were never optimized for high speed connections. The tweaks you use for their op syses are useful. However, you will find linux has always been better optimized for high speed and performance.
 
You did not state which version of Linux you were running. However, you may want to look at the following:
 
cat /proc/sys/net/ipv4/tcp_timestamps
cat /proc/sys/net/ipv4/tcp_window_scaling
cat /proc/sys/net/ipv4/tcp_sack
 
You will probably see the number one "1" returned for each of them. If so, all is good. If any of the values returned is zero you can change them with the following command(s):
 
** NOTE, YOU MUST BE ROOT TO DO THIS !!
 
echo 1 /proc/sys/net/ipv4/tcp_timestamps
 
etc.
 
The buffers allocated are based on a lot of factors. Altering the sizes without understanding what the impact is is clearly NOT ADVISED. You can easily make the overall performance of your machine very poor. You may, however, want to look at these:
 
cat /proc/sys/net/core/rmem_default - default rx window
cat /proc/sys/net/core/rmem_max - maximum rx window
cat /proc/sys/net/core/wmem_default - default tx window
cat /proc/sys/net/core/wmem_max - maximum tx window
 
These parameters may be altered as well. But, I DO NOT ADVISE YOU DO THIS. At least until you have a very good reason to do so. By in large, you will find Linux machines' configurations well balanced for performance.
 
As you mention you are just getting "back to Linux" you may want to read up a bit on network configuration. Do a Google search on "Linux TCP/IP Settings" or "Linux Network Settings" etc..
 
Have fun with Linux,
Bill
 
 
 

Quote:echo 1 /proc/sys/net/ipv4/tcp_timestamps
correct syntax being the very essence of success, it should properly be:

[size:4][tt]echo 1 > /proc/sys/net/ipv4/tcp_timestamps[/tt]

(must redirect '>' the output of 'echo' to the above named file)

cheers!
