AFS cache should not be snapshotted

Description

I don't think we do anything special to make the AFS cache not snapshotted. This means that any AFS activity is going to be very slow because the cache gets read from and written to a lot, which Quentin theorizes makes acroread slow, and probably makes the entire login slow come to think of it. We should probably push out an update to the clusters to create another LV for the cache and mount it.

geofft tested this and found no significant performance gains.

There was discussion at 8/18 release team about using memcache. Further testing is required. But this is no longer a quick fix.

  • Status changed from new to closed
  • Resolution set to wontfix

We want to fix slowness by fixing LVM snapshots, not via the AFS cache.
