Three times the data to process.
This gets really nasty when you are sending the display 
over a network (like X to a remote IDL server)

: Wy is true color 3-4 times slower than 8-bit color?  My guess is that
: it's transferring 3-4 times as much data (24 or 32 bits versus 8 bit).

Thats what I see on UNIX/X displays.
