Ensuring that memory is sized appropriately and that the disk subsystems are effective is very important because these will impact server 18 Tuning IBM System x Servers for Performance performance. For example, if memory size is sufficient, the server is capable of caching more data, which results in improved performance. E-mail servers use log files to transfer modified data to an information store.

Often, poor performance is due to bottlenecks in individual hardware subsystems, an incorrectly configured operating system, or a poorly tuned application. The proper tools can help you to diagnose these bottlenecks and removing them can help improve performance. For example, adding more memory or using the correct device driver can improve performance significantly. Sometimes, however, the hardware or software might not be the direct cause of the poor performance. Instead, the cause might be the way in which the server is configured.
