Tuning for Mail Server

When tuning a FreeBSD Box for a Mail Server you must be aware that mail servers will need a very large number of network connections and small amount of data for a short period of time. You can find how many network buffers you use: netstat -m Then you modify the following variables. sysctl -w kern.ipc.nmbclusters=2048 sysctl -w kern.ipc.maxsockets=2048
