They provide a shortcut to locating information in a table by minimizing the number of rows that need to be inspected to return the desired data. Indexes accomplish this by implementing a data structure that helps to keep things organized and makes locating information easier; basically, indexing speeds up the data retrieval process and makes it more efficient, thereby saving you (and your system) time and effort. At the same time, it’s likely some of the default configuration values aren’t what you want and a little optimization is worth your time. When the sample rate is very low, the estimated cardinality may not represent the cardinality of the entire table, and query plans become inefficient. Before jumping in, let me first say you aren’t likely to see a major impact on performance through tweaking MySQL configuration variables, certainly not when compared to other things you might tweak. As mentioned above, my WordPress database size was 286 MB before cleaning up, and after all of the above-mentioned steps, my database size dropped to 96.7 MB. Better is XFS or OCFS2. A good way to check if you need more memory is to look at how many page faults your system has; if the number of faults is high (in the thousands, for example) it means that your hosts are running low on (or potentially entirely out of) available memory space. There are several tips for optimizing MySQL database performance; some of these can get technical, while others are more high level. In newer versions of MySQL, subqueries may already be optimized, so check whether this is necessary.
