Zfs isn't a typical daemon/process. That's like saying databased is a memor= y hog cause it needs a lot of ram for caching. Zfs ram requirements will depend on your file system i/o load, types/sizes = of files, types and rates of file system ops, etc. 512MB may be fine, or y= ou may need 4GB for optimum performance. ----- Original Message ----- From: Yuri [mailto:yuri@rawbw.com] Sent: Saturday, August 20, 2011 01:38 PM To: FreeBSD Questions <freebsd-questions@freebsd.org> Subject: How much memory does ZFS use? Someone told me that ZFS is a memory hog and it should be avoided as such. Is this true? How can I understand how much memory particular kernel module consumes? In Solaris there is mdb for that, what is an equivalent in FreeBSD?
