Re: Copy and Move Paralysis

01-27-2008

I had read in many places that Vista file transfers (copy, move) would be
faster if the feature called “Remote Differential Compression” (RDC) were
turned off. So I did a quickie test today, consisting of copying a 1.91 GB
folder from my main hard drive to a folder on an external USB drive.
Results:

With RDC turned on: 3:23 - three minutes and 23 seconds (with a stopwatch).

With RDC turned off: 2:25 – two minutes and 25 seconds.

So this quickie test reduced the copy time by about one minute, or a 33%
improvement. Not sure it is a valid test, but interesting. I also am
observing much faster file copy and move within my hard drive, remarkably
so. The whole system feels faster. Note that I did not do a reboot after
turning RDC off. I will leave it off, because even though my file
transfers were quite fast before, they are even faster now.

Do other users here have RDC on or off ?

From what I read, it seemed like RDC would be useful for computers in a
network (mine is a stand-alone machine). Anything ‘bad’ likely to happen
from turning off RDC?
