We have been running running arla in production over 2 years.
We have now about 140 Linux-boxes running arla.

* arla does not die when you do "ls -al /afs"

* arla never crashes the kernel, if it crashes only the userdeamon dies,
  which can just be restarted.

* we have expierienced better performance on some operations with arla on
  Linux 2.4 than OpenAFS 1.2.2

* arla's utilities (for ex. vos) does not provide all features you want, we
  use sometimes the openafs-utilities (which are compatible) on hosts that
  run arla.

* arla does not crash or hang the mashine when you disconnect it from the
  network. I do not recommend openafs on laptops.

* arla does not provide a userful filerserver-environment yet. We run
  OpenAFS.

* arla 0.35 does caching on whole files.

I do not recommend arla for Solaris yet. On Solaris we run Openafs.

Arla works fine on *BSD, Linux, and almost fine on Tru64.

Compared to what ? NFS ?

i dont think so.
