Knocked your server down? I can only apologise for this. Can you explain what happened in more detail so I may look into the issue. This plugin has been going for over 5 years and I’ve never had any bug reports about server problems?
Hello, doing more tests I realized that the slowness only occurs when the option “Copy post content images to destination media library?” is checked, removing this option is very fast. I have 52 posts, and each one has an average of 10 optimized images, maybe it’s the size. I checked the indexes of the tables and they are all ok with what is done select.
