This applies both to UP and SMP systems. Therefore it's pretty surprising that you're seeing a slowdown between 5.x and 6.x, so you should try to look into exactly why your system seems to be running slower. Perhaps it's just a simple misconfiguration, or related to some other change you made at the same time as you updated.
