>          Issue Type: Improvement
>          Components: query-hql

> On a large application with many (currently 696) named queries in hbm files we have a performance issue with the QueryPlanCache cache size: 
> The SoftLimitMRUCache used in the QueryPlanCache use 128 hard references, the other being soft references, and this number is hardcoded.
> As we have much more querries in the application, we spend much time in recompiling the same queries when they are evicted from the cache.
> As the QueryPlanCache has a SessionFactoryImplementor as parameter, adding a new parameter to define the query cache plan size would be trivial; what's your opinion about this ?
