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?
