What makes you say this? I have run JFS for years with complete
satisfaction, and I have never logged into an AIX box.
JFS has traditionally been seen as an underdog, but undeservedly so,
in my opinion; one cause might be the instability of the very early
releases, which seems to have tainted its reputation, or the alienness
of its AIX heritage. However, every benchmark I have come across puts
its on par with, and often surpassing, the more popular file systems
in performance. In particular, JFS seems to shine with respect to CPU
overhead.
