--- Comment #2 from Adrianas ---
We do have relativelly big spring based application with ~250mb of jars.
After migrating from tc 7 to tc 8 application boot time significantly
increased. Seems that most of the time is taken by a constant call to
java.util.jar.JarFile.getJarEntry.
Looks like tc8 class/resource loader on each ClassLoader.loadClass(String)
iterates through all jars and asks each jar if resource exists (instead of
caching jar content once in memory).
tc 8 has the ability to read jar contens only once but to enable it we had to
extend org.apache.catalina.webresources.StandardRoot with custom
implementation.
After change total time spent on
org.apache.catalina.loader.WebappClassLoaderBase.loadClass(String) dropped from
87sec to 39sec. It was 40+sec of time wasted on constant jar content check.
package org.apache.catalina.webresources;
import org.apache.catalina.LifecycleException;
import org.apache.catalina.WebResourceSet;
/**
* Created by adi on 09/06/2017.
*/
public class CustomStandardRoot extends
org.apache.catalina.webresources.StandardRoot {
@Override
protected void startInternal() throws LifecycleException {
super.startInternal();
for (WebResourceSet webResourceSet : getClassResources()) {
if (webResourceSet instanceof AbstractArchiveResourceSet) {
// Load Jar Content into Memory
((AbstractArchiveResourceSet)webResourceSet).getArchiveEntries(false);
}
}
}
}
and register custom implementation in TOMCAT_HOME/conf/context.xml
