Here are the latest contest results including 2.5.38 and 2.5.38-mm1
NoLoad: Kernel Time CPU 2.4.19 66.56 99% 2.4.19-ck7 65.77 99% 2.4.19-ac4 66.31 99% 2.5.36 67.45 99% 2.5.36-mm1 67.39 99% 2.5.37 67.25 99% 2.5.38 68.25 99% 2.5.38-mm1 67.17 99%
Process Load: Kernel Time CPU 2.4.19 81.29 80% 2.4.19-ck7 70.14 93% 2.4.19-ac4 71.10 92% 2.5.36 71.04 94% 2.5.36-mm1 70.68 95% 2.5.37 70.51 95% 2.5.38 71.60 95% 2.5.38-mm1 70.49 95%
IO Half Load: Kernel Time CPU 2.4.19 101.39 69% 2.4.19-ck7 75.96 88% 2.4.19-ac4 97.56 73% 2.5.36 79.30 91% 2.5.36-mm1 100.05 74% 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.
