Re: performance test by Phoronix
Some random observations:
- SELinux did not cause any significant slowdown in F10
(I re-ran the test also with SELinux disabled.)
- The mount options for the ext3 root fs as shown in /proc/mounts:
- F10: rw,errors=continue,user_xattr,acl,data=ordered
- Ubuntu: rw,relatime,errors=remount-ro,data=ordered
F10 has disabled relatime as a default mount option.
F9 had it enabled by default. Maybe that's the reason Ubuntu performs
better on I/O than F10.
