Conclusion

Conclusion
VxFS uses in-memory caches for objects that result in improved file
system performance. The cache sizes are controlled by tunables that are
auto-tuned at boot time by the driver. For situations where the
auto-tuned values are not optimal, you are provided with the ability to
set these tunables.
