Any pointers to info on tuning a system for heavy use would be appreciated. I have a system that has been up for 19 hours. 8:16AM up 19:48, 1 user, load averages: 0.08, 0.02, 0.01 maxusers = 64 #> netstat -m 8422 mbufs in use: 8414 mbufs allocated to data 6 mbufs allocated to packet headers 1 mbufs allocated to protocol control blocks 1 mbufs allocated to socket names and addresses 1536/1536 mbuf clusters in use 4124 Kbytes allocated to network (100% in use) 0 requests for memory denied 0 requests for memory delayed 0 calls to protocol drain routines On NetBSD, I was in the habit of running my kernels with the following. Does this have the same effect on FreeBSD, or are there other things to tune? options NMBCLUSTERS=4096 Thanks for your help
