MySQLTuner is a script written in Perl that will assist you with your MySQL configuration and make recommendations for increased performance and stability. Within seconds, it will display statistics about your MySQL installation and the areas where it can be improved. It’s key to remember that MySQLTuner is a script which can assist you with your server, but it is not the solution to a badly performing MySQL server. The best performance gains come from a thorough review of the queries sent to the server, and an evaluation of the MySQL server itself. A qualified developer in your application’s programming or scripting language should be able to work with a MySQL database administrator to find improvements for your server. Once the server and application are optimized well, you may need to consider hardware upgrades to the physical server itself. This is a really useful tool for helping to optimize MySQL performance.Understanding the various my.cnf variables and how they affect performance can seem really complicated but this tool takes some of the pain away and makes it easier to understand the effects of each variable.It is especially useful to be able to see the global memory usage, memory usage per thread and the maximum possible memory usage - that is really valuable information that is otherwise complex to calculate.

Security, speed, compliance, and flexibility — all of these describe lighttpd (pron. lighty) which is rapidly redefining efficiency of a webserver; as it is designed and optimized for high performance environments. With a small memory footprint compared to other web-servers, effective management of the cpu-load, and advanced feature set (FastCGI, SCGI, Auth, Output-Compression, URL-Rewriting and many more) lighttpd is the perfect solution for every server that is suffering load problems. And best of all it’s Open Source licensed under the revised BSD license.

Spotlight® on MySQL diagnoses MySQL problems in real time by graphically displaying all database activity in an intuitive user interface, enabling you to respond quickly to issues that need attention. With Spotlight on MySQL, DBAs or developers running Windows can drill down to locate in-depth information on the source of a performance issue. And because the run-time nature of your MySQL databases is unique, Spotlight calibrates itself to a baseline of normal database activity. This allows Spotlight to automatically establish the speed of the internal flows and other activity indicators. When a threshold is met, Spotlight notifies you using a visual or audible alert. Spotlight on MySQL supports MySQL versions 5.0 or later that employ the InnoDB storage engine.
