Some performance issues to be investigated: 1. In earlier JDKs, the performance was> noticeably better when suspending only one thread. What is the difference in suspending/resuming all thread and one thread in JDK 1.5? How costly is suspending/resuming before and after method invocation? 2. In some special cases 'ThreadReference.frameCount' takes too much time. 12 calls take up to 8 seconds on 2.6GHz Pentium IV. 3. MethodEntryRequest and MethodExitRequest unreasonably slow down whole performance. We use them to track calls to method in a particular class or to any overriding methods. But it seems the performance slows down for any method calls, not even to that particular class. ###@###.### 10/9/04 00:55 GMT
