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

Preliminary, it looks like a lot of things aren't getting cached (isDirectory, lastModified, isFile, children, etc..). This results in a lot of hash lookups. Looks like they aren't getting cached because of mounting?? Not sure. But, I found a problem with my initialization code (see below). It was trying to mount children. I commented out that part and it ran in 251ms. 40% in VFS init if profile CPU time, 60% in actual time. Sometimes jprofiler is weird. public List<Closeable> recursiveMount(VirtualFile file) throws IOException { ArrayList<Closeable> mounts = new ArrayList<Closeable>(); if (!file.isDirectory() && file.getName().matches("^.*\\.([EeWwJj][Aa][Rr]|[Zz][Ii][Pp])$")) mounts.add(VFS.mountZip(file, file, provider)); /****** Doubled speedup when this was commented out!!!!!!!!!!!! if (file.isDirectory()) for (VirtualFile child : file.getChildren()) mounts.addAll(recursiveMount(child)); */ return mounts; } private TempFileProvider provider; protected void setUp() throws Exception { super.setUp(); provider = TempFileProvider.create("test", new ScheduledThreadPoolExecutor(2)); } protected void tearDown() throws Exception { provider.close(); } Bill -- Bill Burke JBoss, a division of Red Hat http://bill.burkecentral.com
