I still think the problem is the catalog, not (mainly) fragmentation of individual files, because even saving new, small files was very slow. Well, I had to do this again on Sunday.

Unfortunately I've not only had data files over that size limit (video editing is wretched) but also index/sqlite files used by things like Spotlight or Aperture which have a grossly disproportionate impact on system performance; in such cases I've used a simple cp/rm/mv script to defragment individual files, which isn't as effective as getting the entire system but much faster and doesn't require a reboot.
