Issue

  • How could we minify js_loader_modules file to improve our page load performance?

Environment

  • DXP 7.1

Resolution

  • Install Fix Pack 11 which includes the following fixes to improve the performance of js_loader_modules servlet.
    LPS-82808
    LPS-83949
    LPS-92402
    LPS-92810
  • Use the following properties to further compress the js_loader_modules file.
    #
    # The GZip filter will compress files using the specified compression level.
    # Set the value to -1 to use the default compression level. Set the value
    # between 0 and 9 for other compression levels as documented in
    # java.util.zip.Deflater.
    #
    gzip.compression.level=-1

    #
    # 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.
