The test below has not been done under laboratory conditions but is
reproducable here and reveals something strange for which one of you
may have a simple explanation.
When a .PPM file (1.7MB) is read in by PaintShop PRO on an NT
client from an NT server it goes more than twice as fast when using
Linux/Samba as server. When doing the same thing on the client using
"copy" (to a local disk) then there is no significant difference
between Linux/Samba and NT4 as server (this is what we expect
because of limited bandwith). Things get worse when using Samba
on OSF1/4.0. Numbers:
NT server -> memory (Painshow pro) 7 sec
Linux/Samba -> memory (PaintShop pro) 18 sec
OSF1/Samba -> memory (PaintShop pro) 90 sec
NT server -> disk (copy) 20 sec
Linux/Samba -> disk (copy) 20 sec
OSF1/Samba -> disk (copy) 30 sec
This is not a benchmark. It is a simple measurement in a real world
situation so please don't flame me. Before diving into the matter
myself I would like to know if there is a simple explanation.
