MySQL Proxy transparently passes information between a client and a MySQL server. The proxy can audit the information flow in both directions and change it if necessary, which could be useful for protecting the MySQL server from malicious queries or for altering the information clients receive without actually making changes to the database. The proxy can also do load balancing between MySQL servers, and perform flow optimization by directing SELECT statements to read-only slave servers, which enhances MySQL scalability by allowing you to add more servers for read operations.

If you use WordPress as your publishing platform and are concerned about speeding up your website, caching will help you. The faster a web page loads, the better the user experience is.

This is how WordPress caching works: it generates a copy of your web pages and stores them in your server as static files (i.e. as HTML documents) and/or cached database queries. Afterwards, when a site visitor arrives at a particular page, the server gives them the cached page rather than re-querying your database and dynamically generating it, thus speeding up page response times and potentially reducing the server resources required for generating and serving a web page.

Swiftfox is an optimized build of Mozilla Firefox. Swiftfox has builds for both AMD and Intel processors and is based on the most cutting edge Firefox source code available.

Help is available in the Swiftfox Forum. If you have questions or are having difficulty with any aspect of using Swiftfox please leave a post on the forum and I or one of the forum members will provide assistance.

There is now an installer available that is distro independent. It is a script that downloads and installs Swiftfox in the /opt directory and attempts to use existing Firefox plugins. The installer is probably the best way for most users to install Swiftfox. If your distro is Debian based you will want to install using the deb files as the apt repository will provide automatic updating. More info is available at the deb file page.

Existing Firefox plugins should work with no additional configuration if you use the installer or deb file. If you install using the tarball or your plugins are not working you will want to make sure plugins are located in the directory ~/.mozilla/plugins or swiftfox/plugins. If you need any help please visit the Swiftfox Forum.
