Hi Guys, Like an Idiot I was Learning and experimenting with Freenas and I tested it out on a RAIDZ pool with only 2GB of RAM. Obviously this didn't work very well but I have now installed 8GB of Ram did a few reboots and i noticed some better performance however When i look at my Physical Memory Utilization neither Active, Cache or wired go above 2GB. It does see all 8GB of RAM because in the graph i have consistently had 5.9GB of free RAM that Freenas will not touch even when I am copying over large amounts of files. Almost like there is a setting that needs to be adjusted for it to use all 8GB of RAM. I tried changing the "vfs.zfs.arc_max" from "1024M" to "4000M" as a quick test just to see if it would start using the extra 6GB and my system crashed with an error saying there was not enough vm.kmem_size memory. I tried looking in the Wiki Doc but i couldn't find something that would help me tune my system. I also tried the Autotune setting, rebooting a few times and this didn't seem to work either.
Can anyone help or point me in the right direction? I was thinking of re-flashing my system with the 8GB installed don't know if that helps
My tunables
vm.kmem_size = 1536M
vfs.zfs.arc_max = 1024M
kern.ipc.nmbclusters = 50000
