Description
from Even Rouault:
if you still use IJG libjpeg, you might find beneficial to use libjpeg-turbo instead. libjpeg-turbo is now used in all major Linux distributions instead of IJG libjpeg and is a one-to-one replacement to IJG libjpeg: same API, same ABI https://github.com/libjpeg-turbo/libjpeg-turbo apparently builds on Windows too (with cmake), but I didn't try myself. libjpeg-turbo is several times faster in decompression, and in compression too, so MapServer could benefit from it both as a consumer (consuming JPEG compressed GeoTIFF through GDAL) and a producer (generating JPEG images). MapCache too, etc...
