The time to start up the application is mostly due to the fact
that there are a lot of objects to be initialized or loaded in 
from disk.

The time it takes to scroll down to the bottom of a document is
a question of how much the application buffers graphically.
As everything is presented in Postscript, it takes a while to 
recalculate the graphics (there are no bitmap-fonts nor
approximations of postscript-fonts, it's the real thing but
this has it's price...)

Compared to X it is still fast :)
