Re: [jboss-dev] Further profling: Where should I focus?

He, hold on here Bill. If you want to measure performance, you have to have huge testing set. Playing with milliseconds doesn't prove anything :( If you measure: ZipInputStream: 256ms. URLClassLoader: 5ms. it doesn't prove anything. ZipInputStream could be affected by thread scheduler and as such not active for some (e.g. 255 ms) time. To prove something is unefficient (e.g. VFS3), you have to create tests that will measure performance in seconds/minutes to measurement don't be affected by thread scheduler or GC.
