Speed Optimizer – The All-In-One Performance-Boosting Plugin

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.

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

I have no complaints only gratitude for a plugin that does its job. I am thankful.

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).

This plugin consistently delivers subpar results. Hours of tuning are usually required to get an acceptable LightHouse score.

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.
