I suspect this may be a problem of qt4 (or may not), as there is a small time lag to open a menu in qt4 compared to qt3 (although this itself is not too slow to be a problem).
Another qt4 program texmaker ( http://www.xm1math.net/texmaker/ ) is running well at my place. It's as fast as lyx-1.4.x. So, this is not a problem of qt4.
