Hi,
I am looking for a good resource for kernel tuning on very high
bandwidth HTTP servers(avg 500Mbit/sec, peak 950Mbit/sec). Today I
faced very unusual situation with 950Mbit/sec bandwidth!
> netstat -m
16962/93488/262144 mbufs in use (current/peak/max):
16962 mbufs allocated to data
1
(3.67469/sec)
thttpd[]: timers - 4420 allocated, 4380 active, 40 free

I faced that problem years ago, contacted the authour, who said:

You're not running out of mbufs or clusters, you're out of RAM.
Don't bump up nmbclusters anymore because you don't need to; instead,
add more RAM.

FWIW, The math you want should be in tuning(7).

The statistics clearly show that you do.
