Processors

The Application Server automatically takes advantage of multiple CPUs. In general, the effectiveness of multiple CPUs varies with the operating system and the workload, but more processors will generally improve dynamic content performance.

Static content involves mostly input/output (I/O) rather than CPU activity. If the server is tuned properly, increasing primary memory will increase its content caching and thus increase the relative amount of time it spends in I/O versus CPU activity. Studies have shown that doubling the number of CPUs increases servlet performance by 50 to 80 percent.
