[OT] any tricks to boost performance of a read-only filesystem?

[Robert P. J. Day]

  not specifically related to ubuntu, but i'm curious -- are there
well-known ways to pump up the performance of a filesystem that is
almost always mounted read-only?

  it's well-known that, once you install everything on your system,
then you should be able to mount the /usr filesystem read only -- at
least until the next time you need to modify your installed packages.

  now, for performance, once can always mount with "noatime" and
"nodiratime" and that applies to any relevant filesystem.  but if your
filesystem will be mounted RO *almost* all of the time, is there a
particular choice of filesystem that will take advantage of that?
