[Bug 693914] Re: Swapon delays boot when mounting swap partition on SSD

[Ron Blom]

It's been almost three years since I filed this and by now I totally
forgot about it.

However I just changed the swap partition in fstab back to the HDD and I
don't see the delay during boot anymore... :-S

Title:
  Swapon delays boot when mounting swap partition on SSD

Status in “util-linux” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: mount

  I recently installed a SSD in my PC.
  Bootchart shows a ~10s delay when "swapon" is busy see: http://img163.imageshack.us/img163/8...ck20101223.png
  After changing the swap partition to a partition on my (rotational) HDD the delay by "swapon" is gone: http://img413.imageshack.us/img413/8...ck20101223.png
