I've been asking myself that question over and over. It is rather
strange IMHO. But the cache trick made me colorize a 2.5 mb (65000+
lines) in just less than 2 seconds. That is not bad considering that you
would only color the whole file once (when it is loaded) and then just
color the visible part which won't be many lines. 
Even to make the user-interface more responsive you could queue coloring
tasks in a separate thread ?

Janus
