WP Smush | Need to sumsh 100,000++ images


I have about 100,000 images to be sumshed.
Is there any other way to do the process faster or speed up the process as this rate it goes i shall take one week or more to complete by that time my new file will be ready for the same. and also after i started the process the server ram and memory is going too high.

What is the best practice for this ?
