Faster file copies in Windows Vista SP1

If you are like me who moved to Windows Vista early, the two biggest pain areas you would see are Outlook 2007 performance and time taken to do file copy operations. I will never go back to Windows XP but Vista should have done better on these two day-to-day areas.

What used to take like a few seconds to copy from your hard drive to a USB thumb drive (or vice versa) in Windows XP, takes several minutes (or even hours as estimated by Windows Explorer) in Vista. Now with Service Pack 1 for Vista RTMed finally, help seems to be on the way for file copy problems. Microsoft is claiming over 50% to 1000% per cent improvements in file copy performance. RTM bits are not yet available for download, so stay tuned for a worldwide verdict on this. In the meanwhile, if you like to understand the under the hoods of technology on how to file copy works in Windows XP, Windows Vista and improvements in Vista SP1 read this in-depth article from Mark Russinovich.

    Hello sir..

    There is a new process which slows down the moving or copying of files in vista. Remote Differential Compression, but can easily be turned off and disabled. In Control Panel, Programs and Features -> Turn on or turn off Windows features -> Search through and uncheck the box with Remote Differential Compression.

    Hope this will speed up the Copy/Move file process without SP1.

    I read this in a technet. i dont understand much about the below info tho.

    It is said to be Vista TCP/IP "Receive Window Auto-Tuning " slows network access.

    To disable it, open a command prompt and type:

    netsh interface tcp set global rss=disabled
    netsh interface tcp set global autotuninglevel=disabled
