In prep for Linaro Connect & the Ubuntu Developers Summit next week
I've put together some performance measurements comparing libjpeg8c
and libjpeg-turbo compiled with it's libjpeg8 compatibility setting.
Quality settings of 95 and 75 are used. Image sizes used are 640x480
Hardware used includes the imx53 QuickStart board by freescale and an
intel core 2 duo in my Lenovo T400.
The results can be found here including both the raw numbers and pretty graphs.
It is my hope that at LC/UDS we will be able to use these numbers to
convince ubuntu to reconsider it's switch to libjpeg8 and instead move
to libjpeg-turbo. The 2x-4x across the board performance improvement
story is compelling not to mention the technical side of it as well.
