We are starting to experiencing performance issues on a server that acts as
the "head" for multiple (31 currently) TSM nodes. This server CIFS mounts
multiple departmental filesystems - all in various EMC SAN's.  Each
filesystem is a different TSM node.

The "head" server is running Windows 2012 server with 12GB RAM and
2-quad-core processor.

Anyone out there something like this?  What are the realistic limits?  I
have tried spreading the backup start times as much as I can.

As expected, a lot of the time is spend scanning files - 1-node is >10M
files.

Thoughts?  Comments?  Suggestions?
