Yep. Well I can see if I can do both test.

One way to find it out .. testing :-)

That sounds like a good thing. But I will need help on oprofile, because I never used it. 
I was planning to transfer my current setup to real hardware. My current setup uses FreeBSD. The reason for using FreeBSD is that jails have little overhead compare to other approaches known to me. Monday I'll  ask at work if I can use a server for this. Then I have some real fast hardware to test on :-).  If FreeBSD is not an option, I can always test on linux, running just one Xorp instance. And loading full routing table.
