I'm runing Quake2 on FreeBSD 2.2.8-RELEASE as a dedicated server.
Quake2 with many players basically slams the UDP layer of my
machine, for those of you who don't already know. :)
Netstat -s reports:
udp:
110301027 datagrams received
0 with incomplete header
30 with bad data length field
1377 with bad checksum
>> 29882 dropped due to no socket
651167 broadcast/multicast datagrams dropped due to no socket
>> 15494 dropped due to full socket buffers
0 not for hashed pcb
109603077 delivered
36475854 datagrams output
Now I have my sysctl variables set up like so:
net.inet.udp.checksum: 1
net.inet.udp.maxdgram: 9216
net.inet.udp.recvspace: 246723
Note that the recvspace is basically as big as I can make it. I
noticed a decrease in the "dropped due to full socket buffers" when I
increased the recvspace from the default 16K value.
I know that the max value is in the kernel somewhere. My questions
are "where?" and "what will this screw up if I change it?".
