There's no sense denying evidence that 2.2 outperforms 2.4 under certain workloads. Instead we should just be more determined to root out all those problems and deal with them. There is no inherent design reason why 2.4 should be slower than 2.2 in any area at all, however, some practical issues, such as IO scheduling still remain and are being actively worked on. Expect backports from 2.5 later in the 2.4 series. For now, the one thing we must not do is risk instability in 2.4, now that most users have switched over to it.
