That's normal, the compilers are delayed. In addition with c2 if you run 
-Xcomp you'll see lots of uncommon traps and interpretation even after 
the compilers come up. Not that it probably applies to you but for c2 
setting a low compile threshold is more stressful than Xcomp unless you 
are trying to stress deoptimization.
