Re: Fourfold decrease in speed of TCPIP interface when changingfrom OpenBSD to FreeBSD stack

It looks like the TCPIP stack may not be the problem and I need to profile my
application and find where it is slowing down.  Any suggestions on how I
should do this (or could you point me to some relevant documentation)?
There is a profiling package, used with gprof, with data uploaded by TFTP. There's documentation in services/profile/gprof/current/doc. You will need to port to your platform.

A less useful alternative is kernel instrumentation.

A quick alternative is ctrl-c your app yourself a few times to see where it is ;-).
