FrameMaker/SAMBA issue

Hi Jeremy,
	Its an honor to receive a reply from yourself.    

In any event,  this performance problem was
originally seen on several of our multi CPU Origin
200 servers when the documentation teams moved
from using Frame on IRIX to NT.  I've also seen
similar results when the files in question reside
on a Linux(ext2) or Solaris file system.  Appears
to be fs independent.

I just finished a test. I did jump the gun as we
basically have confirmed in regards to file type. 
When I load a project in FrameMaker that pulls the
images from a directory with a limited number of
files we do not see any speed issues.  It appears
its totally a file count issue.

If the clients will only be NT4 and 2k, is it
possible to modify the code or pass options to
make scanning large directories more efficient? 
Any suggestions aside from asking the team to
change their work flow? 

take care and thanks again,

Unix is user friendly,  it's just selective about
who its friends are.
