[Bug 600846] [NEW] [STAGING] btrfs performance on SSD 2.6.35-6.9-generic

[Anthony Hook]

Public bug reported:

I installed Maverick from the daily alternate CD and have the following
setup:

50mb /boot ext2 (defaults)
8gb / btrfs (defaults)
32gb /home btrfs (defaults)

When installing, it took over 12 hours to complete the setup.  I have
two ASUS-PHISON SSDs in this netbook.  After seeing this:
https://btrfs.wiki.kernel.org/index.php/FAQ#Is_Btrfs_optimized_for_SSD.3F
I tried to add 'ssd' to my options in fstab, but this still does not
help.
