Vista - 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?

Oh my gosh!!! I can have my life back!!
Turn Remote Differential Compression OFF if you are having any doubts about performance of Vista file share transfers or shared printing.

go to Control Panel / Programs and Features / Turn Windows Features on or off => Untick Remote Differential Compression."

Just do it! Don't waste a big part of you life like I did!
I had not realized how much I depend on file and printer sharing on my little home network until I introduced Vista as a client with an XP machine sharing its files and a printer.

For the printer, "Access Denied" was the first problem that required a solution that could not be dreamed up -- local port defined as //machine/sharedprinter. After that my printing attempts ended the same as any file transfer attempts -- hung explorer and the need to reboot. Of course the print queue remained "hung", requiring another unofficial "best practice" process to clear up.

My problem is assuming I am the one doing something wrong when it was Vista all aloing!

(wondering what to do with all the spare time I just freed up, oh ya, my former life!)

ADDENDUM: I spoke way too fast. It seems to be better but hangs now and then on a print job (at least). I am still wasting my time with Vista.
I haven't found a definitive solution and have tried everything I did find.
