Okay, makes sense then, though it's going to be painful to backup
all those TBs of data again.  I'll test the ACL tricks mentioned
earlier to see if that helps.

Hmm...that's not good news, though it might be alleviated in my case
by the fact I'm creating more virtualmountpoints to give us some
parallelization options.  Three of our clients are Sun X4500 Thumper
units.  A 16TB zpool takes too long to backup serially and way too
long to restore, so I'm breaking them up into smaller filespaces.  I
no longer have any 5.4.0.0 timings from backups with > 5M files, so
I won't be able to run the comparison against 5.4.1.5.  Sorry.

TSM hasn't supported Solaris x86 for very long, so maybe it needs a
little more debugging on the performance side.
