So, what is your impression of the qt4 frontend? Is it slow as hell as
some other reported?
It is slow, more than 1.4 ever was for me. I can notice it
scrolling the User Guide.
If you mean keyboard scrolling, part of the slowness is because I
disabled the key buffering. I want to see profiling statistics without
it. On due time, if it is still needed I will re-enable it.
Key buffering is not the root of this problem. The cpu is pegged at 100%,
so the scrolling could not be faster with buffering. If qt4 were waiting for
keyboard repeat, then the cpu load wouldn't be 100%.
Maybe the qt4 library shipped by debian has some apalling performance
flaw, or missing optimization or whatever. Or it could possibly be in lyx,
but less likely considering that qt4 on windows supposedly is fine.
For now, lyx with qt4 seems to do about 8 times as much cpu work as
qt3 when anything (scroll, resize, typing) happens in the main window.
