The difference from a simple tight loop is that Netflix test throttles all the memory and begins swapping. The CPU is actually low, but the processing is tied up waiting for slow large volume disk IO.
Alex, you need to tell one important detail: for each OS that you tested, at what step count did it start to become really slow, and when did it stop due to error (if you had patience to wait). >From my experience (steps limit: toSlow - toError). Win XP 2GHz 3Gb 32bit 40 - 42 Vista 2GHz 3Gb 64bit 40 - 55 Linux VM 2GHz 1.5Gb 64bit 20 - ... Mac OS X 2.4GHz 4Gb 32bit 60 - 80 I concur that Linux was the slowest of all and Mac was the fastest. > From: Alex Rufon <[EMAIL PROTECTED]> > > Hi Bill, > > (btw.
