If it's at all like what I used to see on PowerMac 7500s, what runs 
at 1/6 speed is anything that uses a timer.  Since MacOS has a lot of 
subtle timed GUI animation, it all runs at 1/6 speed, creating the 
illusion of horrible performance.  This includes everything from the 
normally small delay when navigating down through hierarchical menus 
to the amount of time a button is highlighted after you've clicked it 
to the speed of the zoom rects drawn when you open a folder or 
application.  MacOS uses timers to make such GUI effects feel 
consistent across a wide variety of Macs, and therefore they all run 
slow on MUL if you have the timer bug.

Performance (for me) was perfectly normal otherwise.  I.E., if you 
start up the MacOS RC5 client, it crunches at normal speeds.
