Speed Up Your Web Site With MySQL Query Caching
One of the best ways to speed up your web application is to enable query caching in your database, which caches commonly used SQL queries in memory for virtually instant access by the next page that makes the same request.

SQL Diagnostic Tools
No matter what they say, I don't think it's true. Database 'experts' say that 80-90% of a database's overall performance comes from the SQL code that's running against it. And I just don't buy it. Instead, I think that most of a database's performance comes from optimal design, and after that SQL code comes next.

MySQL 5.4: Up To 90% Faster Response
Sun Microsystems, Inc. today announced MySQL 5.4, a new version of the world's most popular open source database, designed to deliver significant performance and scalability improvements to MySQL applications.

During my years as an application developer I was most in my element when working on projects that involved building applications from the ground up. Somehow taking user and customer pain points and requirements and turning them into a working solution was much more satisfying than upgrading an existing application, fixing bugs, or tracking down and tuning a slowdown, especially when these tasks involved code I had not created.
