Compressing (Gzipping) js_loader_modules file

Issue

js_loader_modules files are taking more time to load which degrades the portal's performance. To identify whether js_loader_modules file is Gzipped or not:

1. Open the portal in Chrome incognito window.
2. Press F12 and switch to the Network tab.
3. Hit http://localhost:8080.
4. Search for js_loader_modules file.
5. Inside Response Header, search for Content-Type:text/javascript;charset=UTF-8

Environment

• Liferay DXP 7.0

Resolution

1. Fix-pack de-55 or above is required.
2. Add these properties in the portal-ext.properties:

   # If the user can unzip compressed HTTP content, the GZip filter will
       # zip up the HTTP content before sending it to the user. This will speed up
       # page rendering for users that are on dial up.
       #
       com.liferay.portal.servlet.filters.gzip.GZipFilter=true
   
    #
       # Enter a URL to automatically launch a browser to that URL when the portal
       # has fully initialized. Enter a blank URL to disable this feature.
       #
       browser.launcher.url=

3. Delete the following folders:

   liferay/osgi/state
   liferay/work
   tomcat/work
   tomcat/temp

4. Start the server.
