Hmm, I think I'm reaching the point where CDT gives a small boost, though, before I try to explain and rewrite OPB's guide, I need to ask a few questions, make a few statements. I hope that Kevin finds the time to respond and point out the wrong ones .

- CDT basicly is an improved Copy-Waza. It's build on the same fundamentals, but is more elaborate. The average gain depends on what frequency you're running, but at 3.6 - 4.0G, the gain should be +/- 6 to 10 seconds (if copy-waza and cdt are done correctly).

- The superpi run can be split up in several segments, two of them are very recognisable (got some graphs, tomorrow). These two segments seem highly dependant of the harddisk and pagefile. OPB: does increasing the pci freq help? The lower the harddisk's latency, the better, right?

- Everyone who's wondering what file he should use:
1 file which is exactly 3x632MB big. The proces of how to create the files has already been told in the second post. Tomorrow there will be a graph.

- OPB: your theory is based on Server03, right? Just because of the LargeSystemCache tweak, which is standard enabled on 03, or is there another reason?

ELMOR: have you enabled the Largesystemcache reg key? Without that, CDT and Copy-waza are useless. (Beardy: that's the setting we spoke about on MSN. Of course it's obvious :p)
