Windows 7 Disk performance is Horrible.
Windows: Windows 7 Professional x64 (6.1 Build 7600) (Obtained from Microsoft MSDN Academic Alliance)
Processor: Core 2 Duo e7400
Ram: 4GB DDR2
Mobo: Gigabyte P31-DS3L
Graphics: Asus 9800GT 512 MB
Prior to installing i moved all my files around on my Sata disk (averaging about 40-50 mb/sec in XP according to windows copy) After the install of Windows 7 I copied files back to their locations on my system drive (Average was 15 mb/sec according to windows, what the hell?)
Also I'm having issues that while copying i wasn't able to stream video via my smb share without it being choppy, and also if uysing any web browser while doing disc intensive actions the browser would go into "Not responding" mode.
This is further illustrated by that when I work in Adobe After Effects, if i move the timeline slider to fast (disc access intensive) the program will instantly go into Not responding mode and I'll have to restart it.
I've tried to fix this with several methods, among them turning off write cache buffer flushing on the drives (did bring the resource drain down a bit, but didn't help for speed or non responsiveness)
This is really a shame since I've been looking forward to using Windows 7 since the RC ran very well. unfortunately since Windows 7 is unable to run disk intensive applications such as video editing it looks like I'm going to be forced to move back to Windows XP =(
Anyone know a sollution?
