-The original patch was written by jeroen@linuxforge.net
-
-Benchmarks by graysky
-
-Three different machines running a generic x86-64 kernel and an otherwise identical kernel running with the optimized gcc options were tested using a make based endpoint.
-
-Conclusion:
-There are small but real speed increases using a make endpoint to running with this patch.
-
-Details:
-1) Three test machines: Intel Xeon X3360, Intel i7-2620M, Intel Core i7-3660K.
-2) All ran the make benchmark (linked below) 35 times while booted into a 'generic' kernel. Then all ran the same make benchmark 35 times after booting into an optimized kernel. Below are the optimizations chosen for each machine.
-2a) X3360 = core2
-2b) i7-2620M = corei7-avx
-2c) i7-3660K = core-avx-i
-3) Analyzed resulting distributions for statistical significance via ANOVA plots that clearly show statistically significant albeit small differences.
-
-Links to ANOVA plots:

-http://s19.postimage.org/ozwomuak3/core_avx_i.png
-http://s19.postimage.org/d0l6fj4z7/core2.png
-
-Discussion:
-1) All the assumptions for ANOVA are met:
-*Data are normally distributed as show in the normal quantile plots.
-*The population variances are fairly equal (Levene and Barlett tests).
-
-2) The ANOVA plots clearly show significance.
-*Pair-wise analysis by Tukey-Kramer shows significance at the 0.05 level for all CPUs compared.
-Below are the differences in median values:
-
-core2 +87.5 ms
-corei7-avx +79.7 ms
-core-avx-i +257.2 ms
