[Gluster-users] Gluster caching behaviour

[Nguyen Viet Cuong]

Hi Marcus,

I found a very good tuning guide from Red Hat.

http://www.redhat.com/rhecm/rest-rhecm/jcr/repository/collaboration/sites%20content/live/redhat/web-cabinet/static-files/documents/20120530-Tuning-Red-Hat-Enterprise-Linux-6-for-databases

If you use RHEL 6 or the like, you should consider to install tuned &
tuned-utils and activate the enterprise-storage profile as the baseline
before going to more advanced tuning.
