2.4.19-ck7 75.96 88%
2.4.19-ac4 97.56 73%

2.5.37 77.69 93%
2.5.38 81.26 90%
2.5.38-mm1 82.52 87%
IO Full Load:
Kernel Time CPU
2.4.19 170.70 41%
2.4.19-ck7 90.95 74%
2.4.19-ac4 105.53 68%
2.5.36 197.08 36%
2.5.36-mm1 220.14 33%
2.5.37 209.75 33%
2.5.38 170.21 42%
2.5.38-mm1 434.41 16%
Mem Load:
Kernel Time CPU
2.4.19 93.33 77%
2.4.19-ck7 123.15 57%
2.4.19-ac4 117.09 61%
2.5.36 121.02 59%
2.5.36-mm1 100.47 73%
2.5.37 104.75 70%
2.5.38 104.22 70%
2.5.38-mm1 92.97 77%
As you can see, 2.5.38 is improving in most areas. 2.5.38-mm1 has excellent
performance under mem load now, but exhibits significant slow down under full IO
load.
To reproduce full IO load, continuously copy /dev/zero in Ram sized chunks to
the same disk and conduct a kernel compile on that disk and time the kernel compile.
