Libjpeg-Turbo vs Libjpeg8c

What is the difference in performance as measured with tjbench and standardized images
- qualities 75 and 95
- architectures x86_64, x86, armel
- libjpeg8c vs libjpeg-turbo-1.1.90-r722 built with libjpeg8 compat on
- Test images from : http://www.imagecompression.info/test_images/
- gcc version build with -O3 gcc version 4.6.1
- oneiric 11.11
- one fix was made to libjpeg8c to jdmaster.c jpeg_calc_output_dimensions to fix a floating point exception.
