> ## Memory usage

> Many of the techniques for improving server performance involve using memory to avoid disk I/O whenever possible. In general, you spend memory to improve performance. However, if the amount of memory on your system is limited, you can overload memory resources, causing your system to page. Paging can affect performance more severely than a reasonable amount of disk I/O. You must determine the point where memory use and disk I/O is balanced to provide optimal performance. In other words, you must budget the amount of memory you can afford to spend to improve performance.
