OK, so while HDV rendertest only shows a slight speed increase (1:36 V9 vs 2:00 V8), rendering to Sony YUV avi (which BTW produces exactly the same filesizes as Uncompressed) really IS faster; so much so that for the first time I have noticed a substantial difference of my disk drives, affecting CPU usage dramatically.
While rendering a 42 secs long fragment (1920x1080/25p with quite heavy CC and blur added) to the faster drive (RAID 0 capable of well above 210 MBps) takes 30 secs (with CPU usage below 30%), the same job but writing at my slower drive (capable of some 110 MBps) needs as much as 49 secs, and CPU usage is almost 70% !
I never noticed such dramatic influence of HDD speed bottleneck in V8 - I guess that for utilizing the potential of Vegas I will need to build another, even faster RAID (of course if I start using intermediates for some reason; so far never did in real projects).
BTW: looks like SCS changed their YUV codec; it used to produce slightly compressed (smaller) files than uncompressed creates. Now the output files are identical in weight.
