Servlet Filters

Web Space Server comes by default with a number of servlet filters enabled and running. It is likely that for your installation, you don't need them all. Two filters that you can disable without any impact are the Compression Filter and the Strip Filter. These filters are responsible for shrinking the size of the response (to save bandwidth). The Strip Filter removes whitespace from the response object, and the Compression Filter compresses it. This obviously requires some processing, and so disabling these two filters can enhance performance.

To disable a servlet filter, simply comment it out of your web.xml file.

If there is a feature supported by a servlet filter that you know you are not using, you can comment it out as well to achieve some performance gains. For example, if you are not using CAS for single sign-on, comment out the CAS Filter. If you are not using NTLM for single sign-ons, comment out the Ntlm Filter. If you are not using the Virtual Hosting for Communities feature, comment out the Virtual Host Filter. The fewer servlet filters you are running, the less processing power is needed for each request.
