FreeBSD Network Stack Optimizations, Robert Watson

FreeBSD Profiling, Kris Kennaway, MeetBSD 2008

Kris presents some tools to help evaluate performance on FreeBSD and help you figure out what to fix. He explains that performance is a relative term to the workload you are running. A high performance web server may mean nothing to you if your workload is a database.

One of the first things  he recommends is identifying the bottleneck. He lists several things that are common trouble areas and notes that the problem could be from an external source.
