It sounds like the overhead of sending all those checkresults up the tree 
is slowing you down. I think there is a extra called OCSP sweeper that 
will batch up the updates and send them in larger chunks. The key is make 
the OCSP command on the heavy duty machines as light and quick as possible 
and have a slightly heavier process upload them via nsca less often. You 
could use OCSP sweeper or a custom script to do the same thing.
