FrameMaker/SAMBA issue

        Over the last week or so I have been
trying to
discover exactly what the issue is with Adobe
FrameMaker and SAMBA.  I think I may be able to
put my finger on it now.  I hope someone of the
SAMBA developer team will be able to take a look
at the code and correct this if it is in fact a
bug in the code.

Users working on FrameMaker projects served from a
*NIX box running SAMBA, (only tested this on IRIX,
linux and Solaris) experience sub acceptable
performance with page refresh/loads.  The same
projects served from a native NT file server
allowed users to experience near local
performance.  The same projects served from the
same *NIX box but via NFS (NFS service installed
on NT client) seen near local performance. 
Indicating perhaps an application issue.

The image format of choice by FrameMaker folk tend
to be TIFFs.  SAMBA it seems has a hard time
opening Tiffs in an efficient manner.  Replace the
TIFFs with almost any other image file format and
performance shoots threw the roof even if they are
of the same size.  (thankfully microsloth didn't
use tiffs in any of the benchmarks  they
sponsored).  In a high debug mode you can see
SAMBA stuck in a routine that it seems to execute
several times per TIF file.  I also noticed if you
reduce the TIF to 256 shades of gray things speed
up considerably as well.
