Real Usage Performance
So I tried RTM with an oldish, decent computer (Athlon XP 2.4Ghz, ATI 9600XT, 1GB DDR400, HDD scored Experience Index 4)
3rd party software generally performed great, as indicated in the article, but many shell-level things had dreadful performance. For example Browsing folders was much slower than XP, all the thumbnail/file detail/metatag processing slowed things down. Also, ZIP processing was ridiculous, extracting ZIP files was at 250 Bytes/Second. Using 7-zip on Vista on the same file was at least 10x faster.
Also, there were some serious latencies in other things, like when Windows switches off Aero every time certain apps run, the whole system pauses for a while, until the Gfx can reload.
While I'm ranting...When the screen dims to show the UAC dialogs (surprisingly often), the whole screen goes black for about 1/2 a second. This is seriously disturbing the first few times it happens.
