Performance bottleneck in LiferaySharedPageTop due to SAXParser not being reused

    XMLWordPrintable

    Details

      Description

      The LiferaySharedPageTop class exists in order to remove duplicate JSF-added resources from the <head>...</head> section of the portal page.

      It does this by parsing the XML from the "LIFERAY_SHARED_PAGE_TOP" request attribute with a SAXParser instance. But since a new parser instance is created each time, it suffers from a performance impact, as described in the following article:
      http://www.ibm.com/developerworks/xml/library/x-perfap2/index.html

      The proposed solution is to reuse the parser instance.
