hi,

i've noticed that the console on my classic II is really slow when 
scrolling, deleting lines, and pretty much all the time. i've come to 
the point where i actually run x on it (i really laughed when i saw "row 
bytes: 64" for the first time), with the tiny matchbox wm and a full 
screen xterm, since it feels so much faster and more responsive even 
though i only have 10 megs of ram and no fpu.

anyway, to the point: i'd like to know if anybody has any idea why this 
might be? is it the frame buffer code, the font handling, the terminal 
emulation, or something else? i have a dark past in games programming, 
so i know a lot about graphics performance and asm optimizations of 
graphics code, and i'd really like to help out doing something about this.

there's always the possibility that i have something misconfigured and 
that my kernel config could be tweaked to fix this, and in that case i'd 
like to know how. i'm using the intvid at obio graphics driver and all 
the grf and whatnot emulations enabled.

thanks,
