It wasn't a good night for benchmarking. I had a typo in the script to run chat reniced and as a result didn't collect any numbers for this. In addition, the kernel with Davide's patch failed to boot with 8 CPUs enabled. Can't see any '# CPU specific' mods in the patch. In any case, here is what I do have. -------------------------------------------------------------------- mkbench - Time how long it takes to compile the kernel. On this 8 CPU system we use 'make -j 8' and increase the number of makes run in parallel. Result is average build time in seconds. Lower is better. -------------------------------------------------------------------- # CPUs # Makes pre10 pre10-G1 pre10-Davide -------------------------------------------------------------------- 2 1 189 190 185 2 2 370 376 362 2 4 733 726* 717 2 6 1102 1082* 1077 4 1 101 99 101 4 2 199 192 195 4 4 387 382 381 4 6 581 551 568 8 1 58 56 - 8 2 110 104 - 8 4 214 204 - 8 6 314 305 - * Most likely statisticly invalid results.
