Amazon S3 + Smush Pro

Hi there,

We are interested in signing up with WPMU to use WP Smush Pro (and potentially Hummingbird). We are looking at utilizing Smush Pro to resize and optimize 80,000 images. The concern is around performance. If we have Smush Pro compress our existing media library, will the we notice a large server performance hit? How does it perform the compression process on the library?

The second question is around Amazon S3. We use S3 for our images currently using this plugin: If we generate compressed images, and multiple sizes, are these all automatically sent to S3? Can you provide any information about how your plugin interacts with S3?

Thank you,
