So after some experiments I'm off. I was interested because one of my friend from ISP guys did this with his linux. The reason to discard this approach is having to maintain two copies of data. My friend somehow has 64G of ram and he syncs the data from working ram to hd before reboot. There are no simple way to do this on FreeBSD. You have to cook your image manually. Booting from image is not a long process, but even the gzipping the cooked image back will take a while. So, I'm probably will remain using zfs. With this it works pretty fast anyway: vfs.zfs.arc_min=1073741824 # 1GB vfs.zfs.arc_max=4294967296 # 4GB vfs.zfs.arc_meta_limit=3221225472 # 3GB On Fri, 2014-12-05 at 06:24 +0200, clutton wrote: > I'm going to try.
