Vista - Really slow copy/move and delete, & maybe reading

Hi,

I'm running Vista x86 RC2 and have noticed really poor copy speeds. When I copy files that are 100MB or more I can get around 40 MB/s. That's copying from one drive to another (sata drives).

But when I copy smaller files around 100KB then I can only get copy speeds of about 7 MB/s. This is about half the speed I can get in XP. Also, when I try and delete a bunch of these 100KB or so files, it seems to take a really long time.

Anyone know what's going on with that?

Yes, I've see that too. The problem is worse over a LAN/WAN connection,
especially if you try and transfer large, single files (See my post on this
elsewhere in this newsgroup). I'd suggest you try a command line transfer and
see how that performs.

Hello, I see this too, but I have *some* resolve for you...

The first thing I always do, as force of habit, is to go into my network
properties and lock my network controller to 100MB Full Duplex, but when I
did this on Vista my network performance became AWFUL!!! As you mentioned,
copying files on the network could never exceed 5-10% utilization.

So with Vista, I have to use "Auto Detect" for the network settings, and it
is much better, but still not perfect. When copying large files, I get huge
bursts of up to 90% utilization, and then usage drops all the way to zero
for a couple of seconds, and then bursts to the top again... avg.
utilization will be about 40-50%. But, at least I can work now! When I first
encountered this problem the network performance was so bad I was wondering
how long I'd be able to stick with it!

It's possible these problems are related to some network gear that doesn't
support the TCP advanced window sizing enabled by default now in Vista. You
can use a NETSH command to disable this behavior and see if your transfers
work any better.
