the blacklist config option should satisfy your needs;

All of the above to be found @

- dont use ZendOptimizer; in the old days we had bad experience with it 
as it was only optimizing the code on every run, though did not cache 
the optimized code; this resulted in much less performance than caching 
accelerators like apc, eaccelerator and the others provided. I however 
have no figures on the performance of recent versions of ZendOptimizer+

- we used e-accelerator with excellent success throughout the last few 
years, however

- (advice): we recently switched to xcache as of being packaged within 
Debian/Ubuntu, and thus aviuding the pain to recompile e-accelerator on 
each and every PHP minor Version update.
