That is a difficult question (I am sure Stan might have input as well),
but generally the savings of OCTCOMPed CM programs (or user SLs) should
be much higher than the effort for additional switching.
OTOH, I think your performance tool will simply report more switches
per second, because the CM part of your code is executed faster, when
OCTed.
 
From 6 years of support experience I remember only one example where
OCTing a CM program made things worse; that example was the CM PASCAL
compiler.
 
Goetz.
