Settings to speed up network

[Franklin]

Hi forum,


I just upgraded our network to fiber cable and the speed should be 50Mb download and 20Mb upload.
However when I tested the speed it didn't reach the speed.

I found some discussion on the internet, one said that he changed the following setting on his ubuntu box:

[The following information is from http://tekibrain.blogspot.com/2011/07/5 ... linux.html but the page's in Chinese]

add the following lines to /etc/sysctl.conf and then run sysctl -p:

net.core.rmem_default = 256960
net.core.rmem_max = 256960
net.core.wmem_default = 256960
net.core.wmem_max = 256960
net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_sack = 1
net.ipv4.tcp_window_scaling = 1

However, when I setup the above sysctl settings in my server which ran Mageia 1, the speed didn't change. It was still about 20Mb download.

Do you have any other idea about how to speed up the network, or say, to run fully speed in Mageia 1?


Thanks,
Franklin

How do you measure the speed you obtain? In case you take the download speed indicated by your browser, be aware that the speed indicated will be determined by the slowest item in the path taken by your data: and often that is the speed with which the server debits data (rather than the speed of your network). And - in the case of a public server - that debit speed might not be the limit imposed by the capability of hardward and software, but a value selected by the system administrator.

IIUC he only meant his LAN, but without clarification we won't know for sure ...
