Hello Ara, my tests with libjpeg-*turbo* are even more promising. The following comparison between LCL and libjpeg-*turbo* was made decompressing for about one minute a sequence of several 4000x3000 JPEG pictures. The results are expressed in "pictures per second" and prove that libjpeg-*turbo* is about 7-8 times faster than LCL: AMD E2-1800 1.70 GHz *Turbo i386-win32* LCLlibjpeg-turboRatio 0.32 2.46 7.69x *Turbo x86_64-win64* LCLlibjpeg-turboRatio 0.36 2.72 7.56xIntel Pentium N3520 2.16 GHz *Turbo i386-win32* LCLlibjpeg-turboRatio 0.41 3.06 7.46x *Turbo x86_64-win64* LCLlibjpeg-turboRatio 0.43 3.35 7.79xIntel Core i5-4300 2.50 GHz *Turbo i386-win32* LCLlibjpeg-turboRatio 1.01 8.41 8.33x *Turbo x86_64-win64* LCLlibjpeg-turboRatio 1.10 9.18 8.35x
