Hi
Very fundamental question this: how fast can one expect to copy a file
between two machines?
With a Gigabit LAN connection between two Windows 2003 Sp2 Servers we are
getting only about 130Mb/s throughput when copying a single stream of files
from a local drive to a network share yet a pure network benchmark shows
around 900Mb/s of raw IP throughput.
We know the disk throughput at both ends is fine and that multiple sources
to one destination scale, its just the single thread copy from one machine to
another that seems dismaly slow.
XP to XP seems much better at around 300Mb/s.
Any help appreciated
