Updated Libjpeg-turbo benchmarks

All,

For those that care about such things, located in the linaro wiki : https://wiki.linaro.org/TomGall/LibJpegTurbo is benchmarking information and numbers from various arm boards and OSes. Much thanks must be given to Chao Yang for collecting the android numbers. The page is an evolving beast but I thought worth drawing your attention to.

OSes include: Android 2.3.5 Linux (Linaro natty)

Libs measured include: libjpeg62 libjpeg62 + android extentions libjpeg-turbo - 1.1.90 libjpeg-turbo - 1.1.90 + android extentions

I've also included some some graphs for those that might want a higher level comparison.

I will at some point add libjpeg v8 numbers into the mix.

Feedback most welcome.
