Multithreaded option?

[andrew-bydlon]

Is there no option to multithread the procedure. For batch processing on modern computers, this seems essential.

Here is a simple way to handle it:

N = 16 # Number of threads
for file in * ; do #where * is the directory of interest)
((i=i%N)); ((i++==0)) && wait
jpegoptim $file &
done

This is really needed, seems dumb simple to implement, and would increase speed by number of cores

Currently, as jpegoptim takes just a list of files to compress, you could write a script to stupidly cut the list of them to N number of cores and launch as many jpegoptim processes

Initial parallel processing support has been added (to 1.5.0beta). It can be enabled using --workers=maxthreads option.

It has not been tested much, so any feedback/test results would be much appreciated...
