Considering the rendering speed in my old laptops, and what place describes, I guess drawing is taking different function paths in FLTK depending on double-buffering and the detected capabilities of X (something similar to what happens when using the VESA path instead of the native mode with some video cards).
Antialiased fonts are extremely slow on his system, and that looks like something fishy is going on.
That's what I think now as well. 4s per page is very slow. I almost finished to reinstall my old Extensa 367T which has a 200Mhz Pentium and a Neomagic graphics card. It should be pretty comparable to the thinkpad 380XD.
I see that if I switch from 16-bit to 8-bit, drawing a page goes from 4 seconds to maybe half a second.
(I'm not using 24-bit because neomagic(4) says "All depths are accelerated except for depth 24 which is only accelerated on NM2200 and newer models." This has NM2160.)
I'm seeing this now on my old laptop with the Neomagic card. Antialiased fonts are horribly slow. They get pretty fast however if I comment out disable_double_buffer(). I think this is a driver problem, but I will need to do some more tests. Are there any other users with old hardware (slow CPU, but perhaps other graphics card)? Johannes
