"If that's what you're doing, it's not a fair comparison." Fair or not, its a real world comparison. I started doing beta software testing for major software companies (microsoft, oracle, borland..etc) back in 1989....as a former software engineer, I know the process and drill. Yes, I could spend hours trying to configure poorly configure software, but frankly, the onus of that is on the company who creates the software. yes this is betaware...but surely, the configurator under such a scenario should be very conservative in this type of environment. however, if there is lag in basement movement, then, cached or uncached, thats just bad software. anyways, i dont want to debate this anyone. i've commented on my experience. and hopefully this forum is read by the engineers who can contact me directly. cheers.
