Vista Service Pack 1 tested early

By on February 8, 2008, 5:11 PM
Microsoft has talked and talked about how SP1 will give a big performance boost to Windows Vista, particularly when copying files. While everyone will be able to check performance for themselves next month when Microsoft finally releases SP1, the folks over at PCWorld have taken an RTM version of SP1 for a spin to see what kinds of improvements users can expect.

Shut down and boot appears to be slightly faster with SP1 installed. However, when it comes to file manipulation, results thus far have been a mixed bag. A large file copy involving 562 images for a total of 1.9GB from a 2GB Kingston SD Card to the PC was 9% quicker on SP1, while a couple of smaller file operations actually took about 3% longer on a test machine with SP1 installed. Check out PCWorld’s performance test results here, plus some less-promising ones at ComputerWorld.

Doesn't look good. I was hoping they would say its now as fast as XP or faster. I don't think its possible with this OS.

Actually:(This alone is worthy of front page news Julio :P)The reason Vista is slower, is they removed the transfer cache on large files. On XP, when you transfered a file it got transfered to a cache, and then transfered to the new location. This caused some nasty problems in same cases with the ram (Google it if you want more info)In Vista, they decided to just have direct IO operations. That means no cache, just copy it directly. This was supposed to speed it up, and solve the memory problems. The problem is, if you have an antivirus program for example, it wants to check the file as you copy it. This greatly reduces the speed, as it has to wait to be scanned first. So, in SP1 they are bringing back the cache. That is their huge speed improvement.

I havnt read the review yet, but thats interesting never the less.
