Hello,
I'm not sure I'm posting to the right list since luci seems to have a
different mailinglist so I'm sorry if I'm sending to the wrong one.
Some people have modded their routers and added support for different
storage devices and I suggest a change to the current swap space
implementation.
Currently, evey swap space, either created using the interface or uci
is mounted with incremental priority. It may be possible to achieve some
performance increase if the interface(s) would allow striping the swap
space accross several devices given that Linux supports striping by
default with no modifications.
Every new swap space partition is set-up with defaults (I'm sorry, I
forgot to partition and I'm using a swapfile):
/swap/swapfile_1 none swap sw 0 0
However, by hacking /etc/init.d/fstab and adding pri=1 as a mount
option:
-echo "$device none swap ${noauto}sw 0 0" >> /tmp/fstab
+echo "$device none swap ${noauto}sw,pri=1 0 0" >> /tmp/fstab
You can get the striping:
# cat /proc/swaps
Filename Type Size Used Priority
/swap/swapfile_1 file 2040 264 1
/swap/swapfile_2 file 2040 272 1
In my case, I'm unsure whether this will yield any performance but
present or future hardware mods might benefit from it.
Maybe if you implemented some method (via uci for example) to specify
the mount options for swap, one could benefit from this (old) striping
option and avoid manual hacks to /etc/init.d/fstab.
Best regards,
