I'm in a slow machine with only 4GB memory, and I am clearly swapping all the time. htop reveals that the task eating the most memory is the webbrowser (chromium), with 12~18% of the memory, with the second place going to something with 3 or 4% memory usage. Am I mistaken or Ubuntu 14.04 LTS has tmpfs enabled by default? If so, I'd assume that the memory is being shared with TMPFS, which would then easily fill 50% of the memory in one strike (just the cache of the browser could eat that fairly quickly).
Code:
sacrispada@localhost ~ cat /etc/mtab/dev/sda6 / ext4 rw,errors=remount-ro 0 0
proc /proc proc rw,noexec,nosuid,nodev 0 0
sysfs /sys sysfs rw,noexec,nosuid,nodev 0 0
none /sys/fs/cgroup tmpfs rw 0 0
none /sys/fs/fuse/connections fusectl rw 0 0
none /sys/kernel/debug debugfs rw 0 0
none /sys/kernel/security securityfs rw 0 0
udev /dev devtmpfs rw,mode=0755 0 0
devpts /dev/pts devpts rw,noexec,nosuid,gid=5,mode=0620 0 0
tmpfs /run tmpfs rw,noexec,nosuid,size=10%,mode=0755 0 0
none /run/lock tmpfs rw,noexec,nosuid,nodev,size=5242880 0 0
none /run/shm tmpfs rw,nosuid,nodev 0 0
none /run/user tmpfs rw,noexec,nosuid,nodev,size=104857600,mode=0755 0 0
none /sys/fs/pstore pstore rw 0 0
systemd /sys/fs/cgroup/systemd cgroup rw,noexec,nosuid,nodev,none,name=systemd 0 0
mtab seems to suggest that only 10% of my memory is reserved for that purpose, but it doesn't "feel" like so! Maybe I could disable TMPFS overall, to see if it changes? services --status-all doesn't seem to show anything tmpfs-related, but then again I'm not really a specialist in non-OpenRC builds.
