Hi,

My new server has 2 x X5570 CPUs.

Now here is the output of grep -i hz /proc/cpuinfo

model name : Intel(R) Xeon(R) CPU           X5570  @ 2.93GHz

It always remains the same.. no matter how much load is mysql or any other app hogging. Even when mysql eats 2 or 3 CPUs at 100% each, the output of cpuinfo is the same.

If fact mysql performance for some heavy inserts is poorer than my old E5430 server.

Any clues? I contacted the server provider, they tried turning off SpeedStep and still we see the same results.

Any insights would be helpful cause I am paying heavily for this box and would love to milk all juice i can.
