libjpeg-turbo

Benchmark libjpeg8c with tjbench

Registered by Tom Gall

With Ubuntu switching to libjpeg8, we need to collect tjbench performance information for the purposes of comparing intel & arm architectures between libjpeg8 and libjpeg-turbo compiled with libjpeg8 compatibility.

[tom-gall, Oct 20, 2011]: libjpeg8 is throwing floating point exceptions when hitting color ppm images
[tom-gall, Oct 21, 2011]: full collection of numbers complete except libjpeg8 float point exceptions. We have a minimal story for LC/UDS

Headline:
Performance measurements between libjpeg8 and libjpeg-turbo with libjpeg8 compatibility has been made using tjbench on both intel and arm hardware.

Acceptance:
A wiki page has been created with appropriate graphics and numbers comparing the various derivations. Both small and large images has been tested as well as quality numbers. An announcement has been made to the dev list as well as to the libjpeg-turbo list.
