HP-UX Encrypted Volume and File System Performance and Tuning

Summary: VxFS Tuning
Most applications are more similar to random read and write operations than sequential I/O.
Applying the simple VxFS tunes shown earlier can result in huge performance gains for both EVFS
and clear I/O. In many cases, EVFS might reasonably be expected to not affect application
performance behavior, as long as the CPU headroom is adequate to absorb the extra cycles that
EVFS would require.
