Stellar caching product!

We’ve tested and purchased a lot of caching plugins this year to get an optimal performance profile for our WP SEO offerings. Out of all the free and commercial products we’ve used, Swift Performance is by far the easiest and best one to date.

The challenge with other scripts has been deferring JS and Swift Performance seems to have nailed that! Now, not all JS can be truly 100% deferred but, Swift Performance is a close as it gets without custom coding.

We’re also on the fence about adding installing XVarnish and Swift Performance supports that as well. We have REDIS going and its helped somewhat.

I would highly recommend this product and we’ll be purchasing it for all our future SEO projects.

Disappointed & No Replies To Emails

After all the great reviews on this plugin I decided to purchase it to try. I have been using WP Rocket for awhile now and was hoping this would give even better results and some of the features just looked awesome. Well, installed and just a bunch of issues. Spent hours trying to configure, disabling merging of scripts and all the normal stuff (have done this many times before with other caching plugins) but no luck. I couldn’t even get my CDN (Stackpath) to work with the plugin. I contacted StackPath and they looked at everything as well and couldn’t figure out why it wouldn’t work. I ended up switching back to WP Rocket and right away everything including my CDN worked just fine. I emailed Swift Performance multiple times about this asking for a refund but not even a response to tell me to go away. Not really worried about it since it wasn’t that much money for the pro version, but the fact that they don’t even respond to customer requests is what bothers me. Looks like most people like the plugin, so hopefully it works for them…..but if you need support I wouldn’t count on getting any response.

AWESOME Plugin! Does it all and will get your site rocking fast

I bought the premium version and the support is great! I have a page builder plugin, woocommerce, event plugins, marketing automation tools and a ton of other very heavy plugins and swift still was able to get this site with incredible load speeds.

Stop looking around, go with swift and buy the premium. It will save you a ton of time

Impressive! My first performance grade 100 (A) with load time under 1s

I have never got a performance grade 100 (A) with a cache plugin, not even using a CDN (Cloudflare). This was the first time ever I got it. I first tested the default wizard and my score jumped to 94 – load time under 1s. And after I manually changed the settings on (settings > tweaks > Gravatar Cache) I finally got the performance grade 100 (A) – load time under 1s. I appreciate the amazing work the developer(s) did. Thanks a bunch!


Brilliant, stumbled upon SPL because I started using a related post plugin that uses pure css … Had to find something to cure “Serve Scaled Images” This was the only cache plugin that could do that, AND MORE!!! I was able to delete 4 other plugins with this GEM installed. SO glad I found You! Will definitely consider Pro Version. Thanks, 100 Stars!
