[oe] Performance measurement: Building openembedded-core with and without overclocking on C-i7 2600K

[Ulf Samuelsson]

If anyone is interested...

Same machine in two different configurations.

.........................................................#1...........................#2
P8Z68V Pro
Core-i7 2600K @                             3.4 GHz..................4.4 GHz
8 GB @ ...........................................1333 
MHz...............1640 MHz
1TB WD Black 7200 RPM
Ubuntu 11-10

Almost all source code already in source directory

Building meta-toolchain is 13% faster with overclocking.
