Z, It would be good to respond to questions and provide the requested information before bombarding the list with new questions. -Otto

Isn't confusing toi ask a new qustion with the same Subject. Show the numbers and how you retrieved them. This is system using virtual memory, not all numbers report actial physical memory usage.

Re: swapctl question
Also, why is Firefox 58 taking up about 2 gb of ram when I have 8 (non-multimedia) tabs open?

swapctl question
amd64, 6.2 I have my swap partition set to priority 9 in fstab. Why does swapctl report priority 0? # swapctl Device 512-blocks UsedAvail Capacity Priority /dev/sd0b 11874624 1266232 1060839211%0 # cat /etc/fstab 14d16d0d42a89629.a / ffs rw,softdep 1 1 14d16d0d42a89629.k /home ffs rw,softdep,nodev,nosuid 1 2 14d16d0d42a89629.d /tmp ffs rw,nodev,nosuid 1 2 14d16d0d42a89629.f /usr ffs rw,softdep,nodev 1 2 14d16d0d42a89629.g /usr/X11R6 ffs rw,softdep,nodev 1 2 14d16d0d42a89629.h /usr/local ffs rw,softdep,wxallowed,nodev 1 2 14d16d0d42a89629.b none swap sw,priority=9 14d16d0d42a89629.e /var ffs rw,softdep,nodev,nosuid 1 2 I want to minimize swapping since I am using a mechanical hard disk and thus swap slows things down. I can disable swap if I want with swapctl -d but I would rather not. Thanks
