Just to get the speed baseline:
On my box (x86_64 3500+) the scroll userguide down test takes approx.
7 seconds with xforms. (One of my main reasons for not deleting the
xforms frontend outright. QtX (and of use of it) is still to slow, and
IMHO we need xforms to be very clear about how fast it should be.)
xforms: ~7 seconds
qt3: ~23 seconds
qt4: ~36 seconds
gtk: ~20 seconds
On my plateform WinXP, pentium 4 Mobile 1.80 GHz, I have:
LyX/Qt3: 22 seconds
LyX-trunk/Qt-4.1.3: 34 seconds
LyX-younes/Qt-4.1.3: 16 seconds
If I can achieve 16 seconds on my less powerful CPU, I reckon that, with
a few X11 specific optimisation, you could achieve 8 seconds and be on
par with LyX/xforms.
The tests might however not be entirely fair since xforms is quite bad
at fonts and anti-aliasing. But that difference should not be _that_
big.
I'll fix the last compilation bug so you can test with my branch.
Abdel.
