FreeBSD system profiling and tuning for 10, 11 and 12

[Julian Elischer]

Hi

I'm looking for recent information regarding profiling and tuning in 
FreeBSD.

Google has turned up some links but I think that the best leads are 
still hiding..
  for example I only found 
https://wiki.freebsd.org/NetworkPerformanceTuning recently.

(BTW Anyone who has a moment is encouraged to check if they have 
anything to add to it.)

I am sure there is better information around for profiling the kernel 
and modules,
but I am not seeing "the definitive profiler's guide" out there. I do 
know several people
have blogs that cover this sort of thing. If you have one or know of good
profiling resources we should gather them.. send them to me and I'll 
try make
sure everything is up to date, and put them together in a wiki page.

there is already some stuff there,
(see 
https://wiki.freebsd.org/NetworkPerformanceTuning?action=fullsearch&context=180&value=profiling&fullsearch=Text 
)
but it could do with gathering together.
