hibernate: swap on SSD = not fast
Hi,
Mindful of what Stan Hoeppner in various posts has written about SSD I
thought I'd put swap on an SSD I installed (Samsung SSD 830 128GB) in
order to get superfast hibernate.
Surprise: it is slower than usual and the disk light is on.
swap is here:
+ cat /proc/swaps
Filename Type Size Used
Priority
/dev/sdb3 partition 19535036
0 -1
which is on SSD:
...
/dev/sdb3: LABEL="SSD830.03" UUID="ede71620-d8fa-47fd-8aee-0e8b37f9e982"
TYPE="swap"
...
and this is the kernel cmdline:
BOOT_IMAGE=/SDB2.boot/vmlinuz-3.4.7-nodeb-amd64 root=LABEL=SSD830.02 ro
vga=791 nouveau.modeset=0 resume=LABEL=SSD830.03
Is there an explanation of this? It takes about 20s. to hibernate when
swap is on SSD.
