Tony,

One more way to speed up your submit.  I noticed last night that
Dave Lindner's submits were going much faster than mine.  I also
have occassionally noticed that ODE commands complain that random
NFS filestystems I have mounted on /usr/projects are not responding.
It seems that various ODE commands search /usr/projects.  If you
have lots of NFS filesystems mounted there this can be hideously
slow.  I now figure this is responsible for about half of the time
I spent checking in files, and probably checking them out too.

I have no backing trees mounted there, and if I did that would not be
under my control since odemount decides where to mount things.
I do have shared sandboxes and other NFS filesystems mounted there.

I believe the only reason it should be referenced is to get to the
specific shared sandbox under it.  Nonetheless, certain ODE commands
do reference the parent directory of their sandbox for come reason or
I wouldn't be seeing this problem.

In other words you're saying I can't use shared sandboxes on production
machines.  This directory is the standard place to put all project areas.
If ODE insists on looking at everything in the sandbox's parent directory
then ODE is broken.  The alternative is to place every shared sandbox
located in the production environment in its own unique parent directory.
That should not be necessary.

By the way I don't think that much other activity really goes on in
/usr/projects since virtually every directory in there on any production
machine (and most workstations) is a filesystem unto itself.

This sounds like a problem related to the abyssmal implementation we
have for getting the current working directory, which involves reading
and stating the contents of ".." all the way back to the root.  Some
of the shells insist on doing this at startup, some of the ODE commands
may well do it, too.

That would certainly do it.
