Sorry I miscalculated, 400MB/min. Still much better than it was before.

Adding the ignore directive increased speed significantly. It is
averaging about 1.2GB/min now. The change journal was already enabled
also.

Thanks a lot,

One performance improvement we've done is to get NetWorker to ignore
directives in subdirectories.
We had a system where it was spending 40% of it's time checking for a
file called nsr.dir in each
directory it looks in.
For some reason looking for a non existent file is an expensive
operation on a NTFS partition with a
huge number of files.
You'll also want to make sure you've got the change journal turned on
for that volume, the default
values wasn't big enough for us on our large partition. It improves
incrementals significantly when
working.The following directive placed in the top of the file
system.<< "E:\" >>
ignore
