While profiling netgraph operation on UP HEAD router I have found

I have forgotten to tell that it was mostly GENERIC kernel just built

What is 'profile 2'?
I have thought it is high resolution profiling support. Isn't it?
OK. This is not commonly used so I don't know if it works. Try using
hwpmc if possible to compare.
When you say that your own allocation routines show less time use under
profiling, how do they affect the actual system performance?
