--- Comment #1 from Alex Dupre <a...@freebsd.org> 2011-05-27 14:49:54 UTC --- I've debugged the problem and found the issue. This is the incriminated commit: === While scanning JARs for TLDs and fragments, avoid using JarFile and use JarInputStream as in most circumstances where JARs are scanned, JarFile will create a temporary copy of the JAR rather than using the resource directly. This change significantly improves startup performance for applications with lots of JARs to be scanned. (markt) === The last sentence is clearly false, since JarFile is optimized for random access, while JarInputStream has to read the entire file. I'm attaching a very simple test case, showing the issue. This is a sample output: %java TomcatSlowTest webservices-rt.jar Time elapsed with JarFile (Tomcat 7.0.12): 1 ms Time elapsed with JarInputStream (Tomcat 7.0.14): 458 ms -- Configure bugmail: https://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
