I have Arial Unicode MS and .

Buy a new PC with more than 1.5 GigaHz. As you knwo BibleTime's requirements 
are a PC with more than 1 GHz :)
Being serious now...
I know it's really slow and annoying. On my PC, too.
As you knwo Unicode has thousands of characters. If all of these characters 
are loaded into memory this slows down your PC. It's a problem of X11. 
Windows has the same problem, I believe.

Unicode MS is the biggest font I have ever seen (23 MB TrueType file). I 
think choosing another font will not help you very much.
Qt3 may bring speedups because you can select different fonts for the 
different charmaps to build a complete Unicode font. But for this we need 
fonts which support only one part of the Unicode range. We do not have them.

I think Qt3's speed improvements for unicode fonts will not be really much.

The font problem is now the size and memory usage.
