net.core.rmem / net.core.wmem



Guys,

Having various distributions here I can see the following:

Debian 4.0:
 net.core.wmem_default = 109568
 net.core.rmem_default = 109568
 net.core.wmem_max = 131071
 net.core.rmem_max = 131071

SuSE 10:
 net.core.wmem_default = 262144
 net.core.rmem_default = 262144
 net.core.wmem_max = 2097152
 net.core.rmem_max = 2097152

Fedora 8:
 net.core.wmem_default = 124928
 net.core.rmem_default = 124928
 net.core.wmem_max = 131071
 net.core.rmem_max = 131071


SuSE does set other values in sysctl.conf. There must be a reason to do
so, don't you think?

What does make sense? Does anyone have experimented with these and other
(related) values ? Does anyone have experience with sysctl values in
pure gigabit ethernet environments?

Thx,
 Oliver
