I have programs that run significantly faster when targetting x86_64 (Othello back-end solver, various prime sieves, interpreted simulator, MAME [cf. http://aarongiles.com/pix/benchmarks.png])., where significantly means >10%. I agree I can't qualify my list as "most programs", but on the other hand I have yet to see one of my programs running slower as x86_64 bit mode (though I guess some programs with heavy usage of pointers could be in trouble). Did anyone compare qemu ia32 vs x86_64? Laurent
