[jira] [Resolved] (WW-3941) Performance Problems after Upgrade Project to 2.3.7

["Lukasz Lenart (JIRA)" <ji...@apache.org>]

Lukasz Lenart resolved WW-3941.
-------------------------------

    Resolution: Fixed
      Assignee: Lukasz Lenart

The problem is related to my FileManager refactorings and introduced FileManagerFactory with default implementation

ConfigurationManager#conditionalReload() from version 2.3.7 looks like this:

{code:java}
public synchronized void conditionalReload(Container container) {
    FileManager fileManager =
container.getInstance(FileManagerFactory.class).getFileManager();
    if (fileManager.isReloadingConfigs() || providersChanged) {
    ........
}
{code}

so each time FileManager instance was looked up just to check if
reloadConfigs flag is set to true, but right now it looks like this
and the flag is checked directly

{code:java}
public synchronized void conditionalReload(Container container) {
    boolean reloadConfigs = Boolean.parseBoolean(container.getInstance(String.class,
XWorkConstants.RELOAD_XML_CONFIGURATION));
    if (reloadConfigs || providersChanged) {
    ........
}
{code}

> After upgrading a Project to the latest Version 2.3.7 I figured out some performance problems.
> I have a Action which renders around 240kb HTML Code for an Print View.
> Struts 2.3.4: 5s
> Struts 2.3.7: 15s
> I'm not really familiar with profiling but I guess this is related to freemarker.
> <constant name="struts.freemarker.templatesCache" value="true" />
