Vista RC1 slower than XP

[wulf109]

I read on one site,I think it was TomsHardware that Vista was slower on video transcodeing and encodeing than XP. My very un-scientific test would seem to agree. I installed VistaRC1 on Celeron D 3.33 CedarMill running at 4.0Ghz and it took 19 minutes to transcode a disk that took 18 minutes running XP. It was a 3 hour episode disk transcoded using DVD Shrink 3.2

a. It's a releease candidate and not the gold version, so performance, while close to the final release, may not accuratelt reflect the final version

b. It is well known that Vista has higher system requirements than XP

c. DVD Shrink has not be tuned for Vista, and therefore may not be able to make use of smarter routines that may in fact increase performance

d. It is a about a 5% reduction in speed. On a single test thi sis not signicant or in fact meaningful. Repeat the test 100 times and it will start to have some meaning.

As with any new system, until it is the final release version, with optimised software releases, comparisons don't mean a lot.
