I have a ZFS GhostBSD system which I really like. However when starting the software management tool, it would come up with a memory availability issue for a couple seconds then clear, and proceed to work normally.
Curious about this, and knowing that ZFS uses system Ram for caching I decided to add more memory... moving from 8GB to 16GB and running it at 1600MHz.
System seems snappier, however the ram useage is nearly 80% at times,and is generally hovering at 66% or more. I searched for some GhostBSD compatible command to limit RAM use. However have not found any. Wondering if I should try some Linux or Solaris11 commands?
HELP !
ZFS Memory useage
Re: ZFS Memory useage
add vfs.zfs.arc_max="4G" in /boot/loader.conf that will limit arc to 4GB of ram.
Re: ZFS Memory useage
It is 1GB of RAM per 1TB of HHD.
