Description
I have an iMac with 24GB RAM and ImageOptim is only running one guetzli thread that uses ~1.5GB per ~15MB jpeg. It would be nice if we could choose our own destiny and allow it to use all cores, rather than forcing a single process.
Btw, thanks for implementing guetzli so quickly, this is great!
