These are the exact reasons I stopped to the move to Qt4 and picked up maintinance of Qt3 (now becoming TQt3). I gave the conversion effort my best shot (which took many, many months of effort) and stopped once it became apparent how extensive Qt4's limitations were (especially in drawing operations and native X11 window handling) and also how buggy Qt4 really is.
May I ask for the benchmarking results? I am seriously interested here as I think that I can provide you some valuable help here. My fear is that you had an incorrect benchmark (the experts call that phoronixing) and that your decision is because of that on false grounds.
Especially important is to consider that graphics cards, drivers, what you render (widgets vs scenes), which Qt graphicssystem you use seriously influences the result. E.g. rendering widgets with raster might be a bad idea.
