READ_COMMITTED would actually give you better performance if you don't require REPEATABLE_READ guarantees.  

wakeUpInterval - if you don't need eviction, then remove the whole eviction XML block.  From your initial post it seems as though you were not using it and hence didn't need it?  If you do need it then that's a different story.

Do your reads happen inside of a transaction?  E.g., do you do :

1.  Start tx
2.  Read stuff
3.  End tx

Or were you using "transactions per second" to mean "operations per second"?  

Regarding JVM tuning, that's a whole science in itself and will depend on a bunch of parameters including, but not limited to, system architecture (32 vs 64 bit), operating system, JVM version and vendor, operating environment (e.g., app server config) memory requirements of your application itself, amount of and type of data cached, etc.
