jpcache is written in php and is quite fast.  If you poke around there's a 
comment from the SourceForge development team (when it was an open 
project) that says that jpcache increased site performance about twice to 
four time as something like APC-cache or Zend Accelerator.

FWIW.. unless your application can really take advantage of in-memory 
caches and persistent objects (not connections) you won;t see a lot of 
performance boost.  Keeping the script compiled in memory as opposed to 
just recomplling it on the fly isn't the biggest hit in the php process.  
You spend more time in object and data structure creation and descturction 
that you do with compiling.  Hell, you could get the Zend compiler and 
you'd probably get the same or similar performance.
