Server Scaling
This section provides recommendations for optimal performance scaling server for the
following server subsystems:
■
“Processors” on page 93
■
“Memory” on page 94
■
“Disk Space” on page 94
■
“Networking” on page 94
Processors
The Enterprise Server automatically takes advantage of multiple CPUs. In general, the
eectiveness 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
