I'm running a MARS 50 at an average 70% CPU load during full production. I've always felt navigation through the web interface was a bit slow, not just waiting for the mitigation paths to draw but the whole thing. A few days ago I tried Firefox and the difference was huge although Adobe SVG didn't load properly and the tables were crocked the navigation was almost real time.
I'm not an expert on IE 7 but to me it feels like the difference in speed it too great to be a setting thing.
Does anyone have the same experience?
