Hi, unfortunately i have the exact same issue. My servers have a significantly higher load in wheezy than in squeeze. If i boot the wheezy box with a squeeze kernel everything goes back to normal. A bit more googling revealed: http://stackoverflow.com/questions/12111954/context-switches-much-slower-in-new-linux-kernels http://serverfault.com/questions/530944/mysql-5-5-degraded-performance-in-linux-kernel-3-2-compared-to-2-6 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=693942
But there is no real solution in there yet . The wheezy backports kernel also does not really help. Is there a chance this get's fixed or at least could someone explain why this happend? For now i could run the machines on a squeeze kernel. But that is not really a good plan for the future.
