I don't know yet, I'm busy with viewer, someone else may browse sources for it. I think there will be more places where the interpolation is solved, probably different for vectors, fonts and bitmaps. There are also some space to optimize used libs for decoding Jpegs, Z...

I tried to recompile MuPDF with some better optimizations, maybe help little bit
http://rayer.ic.cz/350d/mupdf_07_dos.zip
-O3 -DNDEBUG -fomit-frame-pointer -frerun-loop-opt -ffast-math -march=pentium-mmx
But I didn't rebuil all libs.
I also changed profiling debug output, you should see total render time and img blit time. I got very different numbers in 2 test case:
real PC: 25 / 24 ms (800x600/32bpp bankswitch (under XP))
DOSBox: 253 / 10 ms - so here you can see the effect of slow CPU but fast gfx.
So it would be interesting what is your ratio (low performance CPU vs low bandwith LFB transfer).
I have VESATEST log from one old Pentium 1 machine with old PCI VGA:

You can download and measure it here
