Subjectperformance of 2.4 vs 2.5
Just for amusement I booted 2.4.18 and ran the numbers. 2.4.20 should be
very similar, I just happened to know that 2.4.18 worked. All on 16x
NUMA-Q w/ 16Gb of RAM.

I think I like the system times for kernbench 256 best (2.4 imploded when
I went higher than that) ... 2.5-mjb = 90s ... 2.4 = 735s. Heh ;-)

Kernbench: (make -j N vmlinux, where N = 2 x num_cpus)
Elapsed System User CPU
2.4.18 83.71 591.42 675.80 1515.00
2.5.64 45.25 109.39 562.69 1484.25
2.5.64-mjb5 43.78 81.58 562.15 1469.50

Kernbench: (make -j N vmlinux, where N = 16 x num_cpus)
Elapsed System User CPU
2.4.18 96.26 735.75 771.56 1562.25
2.5.64 46.32 130.48 566.98 1507.25
2.5.64-mjb5 44.15 90.71 564.34 1485.25

Kernbench: (make -j vmlinux, maximal tasks)
Elapsed System User CPU
