Hi all! I'm using TreeCacheAOP in a webapp. It successfully transmits objects over the network and shares them with other app servers. Excellent!
But performance has been slower than expected (but I'm not pointing fingers here... just looking for some help). I'm using CacheMode=REPL_ASYNC, IsolationLevel=NONE and UseReplQueue=TRUE to increase performance. It is faster, but still slower than expected. A dynamic page that normally takes 25ms to load (with a simple in-memory cache) now takes about 230ms. A tenfold increase. I profiled the app with jProfiler and things like org.jboss.aop.joinpoint.FieldReadInvocation.invokeNext are called any time I get a property on one of the cached objects. I notice things in my classpath like MyObject.myprop$myprop_Get which are certainly generated by the AOP process. I'm using this statement to prepare the objects: And org.jboss.aop.ant.AopC to do the intrumentation. I'm running Java 5.0 with 5.0-style annotations. My question: is there any way to prepare the objects so that the jboss cache overhead is not triggered on property gets? I understand that the cache must be updated any time I set a property, but this performance for gets seems a little slow and I'm not sure what it's doing... since I'm running in REPL_ASYNC mode I assumed that it wouldn't have to do much on the get. I'm not sure whether this is an AOP performance issue, user error (me) or something in jbosscache. The functionality is exactly what I need but performance may be an issue if I can't overcome this. Thanks for any insight you can offer, Joe View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3924789#3924789 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3924789 ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
