No Faults, Works Well on My Site
I have no complaints only gratitude for a plugin that does its job. I am thankful.
Excellent
With this plugin + SiteGround hosting, you can get all of the performance that expensive hosting like Pressable, WP Engine and Flywheel tout, but with better support and way, way cheaper. However, it has a major flaw that SiteGround refuses to admit. If you enable webp images, it will auto-generate those for you from your uploads. However, if you upload your own webp images, and then disable this feature, it deletes all of the webp images you uploaded. I tried to report this to SiteGround, but they insist it is not a bug. Deleting user data without their permission should never happen. Having a feature that, once turned on, can never be turned off without deleting your content, is a bug.
Troublesome plugin
Be very careful of this plugin. Regular warnings from Siteground about the increasing size of my site can be traced back to this plugin storing more than 3GB of cache files, expanded from only a few K a week before, and I”d done no’d done nothing but add a single WC product to my site with a single jpg! Siteground needs to sort out this problem: it’s not new. Clear cache every time you log in the back end seems to be the only way to stop this monster for screwing everything up
Generates 7GB of “optimized files” – worthless
I have to delete 7GB of cached files every 3 days. Receive every week several notices from SG that I have to upgrade my account to more expensive one or delete some (of their) files… Nice trick 🙂 Deleted this plugin asap.

Site Performance throws error
Error We failed to connect to Google servers, please try later! Rest of the plugin seems to work, hence only 3 stars

Nice integration with Siteground hosting
It’s a great plugin for basic and quick optimization. For advanced settings and fine-tuning, look for another plugin. I think a great improvement would be an “Automatic Purge” option or addon. Sometimes when updating a CPT, the plugin clears the cache, but if I have a custom query on another page of the site, the plugin doesn’t know, and that page is never uncached until I manually clear it. The update could be something like: If I update “Books” (CPT) or “Posts,” refresh all cache or refresh the cache for specific pages (with a page selector).

More Trouble than it is worth
This plugin consistently delivers subpar results. Hours of tuning are usually required to get an acceptable LightHouse score.
