fio test results of kernel 2.6.15 - 2.6.24

I have executed the test case of Mathieu Desnoyers on some different kernel version. I took the bad and good kernels from my bisection. The results do not confirm my theory. If someone can identificate a problem in it, I can make some more tests.

The only regression I can seen is the regression with the noop scheduler. It is the average of the average latencies.

./test.2.6.15-53-amd64-genericresult.noop 700,62ms
./test.2.6.20-17-genericresult.noop 3520,24ms
./test.2.6.20result.noop 3005,24ms
./test.2.6.20badresult.noop 3698,64ms
./test.2.6.22.19result.noop 1393,67ms
./test.2.6.24.7result.noop 589,66ms

I will check, if the 2.6.24.7 kernel test build has a improved desktop responsiveness.
