sorry for the delay.
Using 1 BPP may help a little:
1) less memory to handle, gfx routines a bit quicker
2) less DMA load. The DMA load affects the CPU constantly
to build the video signals from the video memory.
A crazy idea: if you can accept it, turn off the video controller (one bit somewhere)
while you build your GUI.
But seriously, I am not extremely shocked by your 4-5 seconds. I should have an idea
of what kind of widgets you display. Do you have bitmaps ? The bitmap format helps a
lot. Taking monochrom bitmaps in PBM format for, say, icons (if you can accept
monochrom icons) drastically improves the perfs.
The VZ at 32 MHZ can still do much, provided one spends some time carefully
configuring things.
You'll never reach multimedia perfs, but there are good chances you can reach
acceptable perfs (The Palm, for instance, does not build its screen instantly, but
quickly enough so that you don't notice this if you're not arare of it).
