Utilizing mySQL, users seek a database management system that quickly and accurately organizes their data. And as with any system you are operating in, you want to get the best performance out of it. Accordingly, there are hundreds of tips out there to help optimize your mySQL. Provided below are some basics for quick and gainful performance enhancements.
Create indexes in your tables so this information is loaded first. Much like using an index in a book, a user can go directly to the indexed topic to find information without browsing through the entire literature.
Another tip is partitioning tables. You will notice a considerable difference in lookup times, especially in tables with thousands or hundreds of thousands of rows. A user can limit the information being scanned and retrieved for lookup optimization and performance gains through either horizontally partitioning or vertically partitioning a table's rows and columns.
Locating and fixing slow queries within MySQL is another quick way to optimize performance.
According to mySQL, examining a long slow query log can sometimes become a difficult task. To make this easier, they suggest utilizing the mysqldumpslow command to summarize the queries that appear in the log.
And always remember, after all the steps taken to optimize your mySQL, be sure to backup your data daily. While a quality hosting service will backup your site daily, it doesn't hurt to take your backup precautions. If you aren't familiar with backup strategies, ask a trusted source, such as your hosting provider, for tips or help with ensuring your site's data.
