1. Re: Questions regarding performance of read-only operations
genman Mar 25, 2007 12:52 AM (in response to haviv.rosh)The calls are made using reflection. The call does not go to the JChannel for local caches.
If you want to find performance issues, I suggest you use a profiler. -

haviv.rosh Mar 25, 2007 2:55 AM (in response to haviv.rosh)OK, so no channel calls are involved, but reflection call on every
getter I call ? Why ?
Second- You are right about the profiling part - I will profile it too, I just compared simple pojo getters against aspectized pojo getter and the results were pretty surprising .... -
3. Re: Questions regarding performance of read-only operations
brian.stansberry Mar 25, 2007 9:52 AM (in response to haviv.rosh)All cache operations move through an interceptor stack that handles aspects like locking, transaction management, and interactions with cache loaders. Replication is just one of those aspects; if the cache is in LOCAL mode the other aspects still have to be properly handled.
An interceptor-based architecture involves an object that carries the invocation through the interceptor stack. In JBoss Cache this object is a MethodCall. Use of that particular class, with its roots in JGroups, is largely a result of JBoss Cache's historical roots. Using that class is a bit conceptually messy, but if we switched to some other class, it would have to perform the same functions MethodCall does.
