Re: Windows Home Server performance - very slow.. any ideas?

["keyvan2r" <k1@xxxxxxxxxxxx>]

Thanks for the post Phil.
The choking is all to do with disk access, its very rare that cpu use
monitore on task manager or performance console runs high. The indicators
which are maxing out are all to do physical disk access seem to be ones
which run to their maximum.
I looked at Drive Extender Migrator (demigrator) and the MS tech brief on
WHS Drive extender which covers load-balancing and duplication.
There does not seem to be that much one can do about it!!!
you can't unistall demigrator becuase then whs won't see the extended
volume. I can't imagine how I would go about testing what h/w combination
is the problem short of building another machine!
All in all, its seems to be hopeless!!
Thanks anyway, will look for more things to try before I go back  to the
drawing board.
