Randall, have you any idea how large you disk cache size is in SL?  And are
you constantly exploring new scenes or revisiting old ones?  The question is
is there a difference between when you are looking at new data vs. cached

I don't know if the Mac has it (though I suspect it easily could) but I find
the gnome-system-monitor (or "top" or "vmstat") to be highly useful in such
situations.  I can watch in "real-time" the CPU vs. Memory Use vs. Network
vs. Disk activity which in complex cases like this is what one needs to
diagnose the problem.  For example I can tell whether I'm using Direct
Rendering of graphics (taking advantage of the hardware) or using Indirect
Rendering simply by watching the CPU load of the program.

Windows also has a "System Monitor" program but it goes a little bit over
the deep end with regard to how much information it gives you (I've nearly
got a degree in Comp Sci and presumably understand all of the information it
can give you but I find dealing with it a royal pain in the a**).  The Linux
tools strike a relatively good balance to allow you to get a good feel for
what the machine is actually doing.

Oh, and for those not following the thread, Eugen is running a glxgears FPS
rate 7x faster than I am which in turn is 2-3x faster than one would get
using indirect rendering (this is on mid-range 2.3+GHz P4 & above
machines).  For a lark I might try glxgears on the 75MHz Pentium downstairs
that is about a decade old....  And "they" say the singularity isn't
