http://issues.apache.org/bugzilla/show_bug.cgi?id=37020 Summary: antiJARLocking and antiResourceLocking with many lib jars causes performance degradation and reload failure. Product: Tomcat 5 Version: 5.5.9 Platform: Other OS/Version: other Status: NEW Severity: normal Priority: P2 Component: Catalina AssignedTo: tomcat-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] Here is a catch-22. We want to use deployer to deploy web applications to target servers. It formalises the process of build a little more. However, deployer does not work well on Windows as JARs get left behind. Furthermore another bug I submitted yesterday shows that deploying, restarting the Windows service and then undeploying breaks. That restart bug aside, in order to even get deploy and undeploy to work we have to use antiJARLocking="true" antiResourceLocking="true" on our context. I added this just the other day and I noticed that starting Tomcat took a whole lot longer than usual (nearly 1 minute), and that compiling class changes to my development Tomcat did not cause the usual web application reload (as indicated by reloadable="true" on the context). I decided that the only thing I changed was the antiJARLocking="true" antiResourceLocking="true" attributes. I took them off today and Tomcat starts up in 20s. Furthermore, compiling class changes works again. I thought about why this might be and we have 18M of lib JARs. In order for the anti locking to work I notice that copies are made to a temp folder. I can only assume therefore that having so many JARs in a web application lib combined with using the anti locking features causes this huge degradation in ability to develop and test. I've made sure this is definately the problem by adding and removing the antiJARLocking="true" antiResourceLocking="true" attributes a few times, and it always varies from 58s and no reloading with them set to true and 20s and reloading ok with them false. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
