Hi @marlinazrin,
Thank you for your review, I’m sorry to hear that you find it slow but please note that there are different factors that affect this.
Image optimization is done on our servers and when process is started your images are sent there, then sent back to your site, depending on your WP setup, image size and the server speed itself smushing time can be different.
Do you have other sites hosted on different server where you can give it another try to see if there’s any difference in speed?
Cheers,
Predrag
