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

For example I just optimized VirtualFile.isDirectory(), isFile(), and getMount() to cache (and invalidate the cache on a mount). In addition, I modified VirtualFile.getChildren() to have the FileSystem create the list of VirtualFiles. Doing so, allowed me to pre-initialize the isDirectory cache of the VirtualFile. I just got a 12% improvement (30ms). This improvement was entirely within determinePackageNames, but still. 30ms * 3 (15 meg of jars) * 2 (Packages + Subdeploy scans) == 200ms less of App Server boot time. Not much, but its a start.
