 Posted: Wed May 22, 2002 6:23 pm Post subject: Tweak Your Connection |
 |
|
Anyone doing any tweaking on there gentoo broadband connection, and if so notice any difference. I sometimes run a RTCW server and the pings are fairly good, but it would seem that I could tweak my connection to have better ping stability.
Cable Connection:
kbs = Kilobytes Per Second
300kbs -- Down
50kbs -- Up

Check out DSLReports.com (bad name -- it isn't just for DSL)
Every broadband tweak under the sun is listed somewhere on that site. (though finding them all can be somewhat of a challenge.)
These are the four that I set on my system:
| Code: | # echo 262144 > /proc/sys/net/core/rmem_default
# echo 262144 > /proc/sys/net/core/rmem_max
# echo 262144 > /proc/sys/net/core/wmem_default
# echo 262144 > /proc/sys/net/core/wmem_max |
This increases the amount of memory available to socket buffers and socket input queues. I got a ~700Kb performance increase on my cable connection after tuning these.
though some people recommend simply tuning the following because 2.4.x kernels are supposed to 'autotune' fairly well:
| Code: | /proc/sys/net/ipv4/tcp_rmem
/proc/sys/net/ipv4/tcp_wmem |
EDIT: There are three valid settings for the above two parameters: "min default max"
BTW, not to be pedantic, but 'b' equals 'bits' and 'B' equals 'bytes'.

I should also note that setting these parameters will chew up additional RAM. If you're regularly hitting swap as it is, these parameters may actually make your system slower.

Ooops yeah I saw I posted that in the wrong place but it was too late 
About kbs vs kBs is why to avoid confusion I put:
kbs = Kilobytes Per Second
Anyway thanks for your input, I knew how to tweak in linux just wasn't sure if it was going to get me anywhere. Although from your above statement it may

That's on a 10Mbps connection, so YMMV.
