What I'm about to say may have nothing to do with your problem, but just 
in case...

Are the 2ms per object just the deallocation time, or is there something 
else involved?
If it's just the deallocation time, it sounds quite high even for a 
"fairly puny CPU". Maybe you're using an allocator that is inefficent in 
deallocations when there are lots of small objects on the heap?
(should this turn out to be the case, I'd suggest a constant-time 
allocator like tlsf).
