Slow File Operations in Vista

I have also noticed that copying [large] files using Vista is noticeably slower than using XP - posting here to remind myself to look into it later...

In fact, it's faster for me to go on my notebook, and connect to my hard disks via administrative shares, and copy them that way; when I do this, the speed approaches 5MB/s, which is still extremely slow compared to how fast it should be able to move files within the machine.

Here's a ton of info to digest if you time to read through it:
http://www.google.com/search?q=copying+large+files+in+vista+is+slow&rls=com.microsoft:*:IE-SearchBox&ie=UTF-8&oe=UTF-8&sourceid=ie7

Go to Programs and Features in Control Panel, and chose the option for Turn Windows Features On or Off.

You'll likely receive a UAC prompt.

Uncheck Remote Differential Compression and click OK.

Enjoy faster file transfers.

What possible negative effects could this have?

I suppose that Estimated Time Remaining might return to being inaccurate as it was in XP and older OS's - not much else.

I tried that, then restarted.  Now, things seem to be even slower than they were before.  Any ideas?

well for start you can reenable the option then - then read through that first link I left you and let me know if you find something that works!

Let me know how things go - I'm [almost] just as interested in a result here too since it's quicker for me to restart into XP and then copy large files from one place to another (ie HDD to HDD, PC to Networked PC, DVD to HDD, etc)

I just went through about the first hundred results of that google search, and didn't find a working solution.  I haven't come across a problem that has given me this much trouble in a very long time.

Well that's not good.
The next place I'd search/browse around  is www.microsoft.com - unfortunately I'm not home or in front of a PC for a the majority of today (it's 7:41am Monday here now)
did i say unfortunately?  :) - bit of sunshines probably good for me

[they] say that if you get 20 mins of sunshine everyday on your face and hands, etc it helps prevent you from shrinking (growing shorter) as you get older - there's one tip for today   :)

I'll check my email again tonight

Thanks.  When I get home today, I'll apply the hotfix mentioned, and with any luck, that will be the solution.  I hope you're right, and that this does get a lot of publicity.

I suppose you are right, and that I should wait.  I'm still keeping an eye open for a solution, though it appears that as of yet, there isn't one.

Eventually hopefully there will be a hotfix.  It is horrible.

count me in as another one - it's bloody frustrating too - i'll have to switch back again.  Every time they pop out something new i want to believe, and they ALWAYS FAIL.  Good thing i carved out my niche managing creative solutions using macs and linux - with this kind of shit going on MS is going to take a beating in corporate sales.

Sorry. l am not the original poster. Mea culpa.

One thing that I just noticed that is also strange is that if I try copying from my 500GB disk to itself, the transfer rates go above 20 MB/sec, but if I try to do this with other drives in my system, they do the old 800 KB/sec thing.

That's been tried - i think it was the first thing for most people with this issue.. also tried, disabling ipv6, differential compression, turning off explorer view, etc, etc.

Autotuning has nothing to do with this issue - and if you reference kb article 770 and 170 none of those things work either.

fair enough - i tried changing the option but haven't copied anything since then

PAQ refund

I'd like to award points, but have no idea how to do so.

There are two links at the bottom of every expert post

One of them says to 'Accept This Answer" - click that to give all the points to person who typed that post.
The other says to "Accept Multiple Solutions" (otherwise known as a "split"). Click this, then EE will load a version of this question that shows ONLY the expert comments (omitting yours and administrative ones). For each comment there is a textbox where you type in how many points you will give to each person/post. You cannot give points below 20 (unless it is 0 (or empty). All the points you give to everyone must add up to the total amount of points you have reserved for this Question.

Then you just give a grade for the solution(s). The better the grade the more points we get. An 'A' grade works as a 4x multiplier, B is 3x, C is 2x. So the real maximum amount of points that an expert could get is 2000 (500 x4).

Sometimes instead of asking for a question to be deleted by the mods, they will just close it and give a lower grade to reward experts for their efforts even if no solution was given.

Hopefully this info helps - there's more to read if you click the Help link on the top-right of any EE page.

Thanks.  I know this.

I meant that I didn't know to whom I should award the points.

I thought you should have known that - I've seen you around for a while   :)
Split with everyone and you can't go wrong

Thanks for the help guys.  I do hope that Microsoft fixes this issue.

Maybe in Service Pack 1, but I hope it's a lot sooner than that.

Maybe they don't even know about it - since they are testing it on computers running at high indexes?
Hopefully I'm wrong - I'm sure there are similar questions on the MS TechNet forums.

Thanks for the points.
