It can merge and minify scripts and styles, move scripts to the footer (without conflicts), and it can generate the critical CSS for each page on the fly, which is unique on the market at the moment.
Swift Performance also provides an unlimited, built-in image optimizer for lossless image optimization. There is an awesome lazy load option, and with the plugin you also can inline small images which can reduce the number of HTTP requests and improve the pagespeed.
The CDN module helps to set a CDN service without an additional plugin.
The cache module has some unusual features as well, like exclude pages based on content part, or the AJAX cache feature, which can speed up AJAX search, or other AJAX requests. The intelligent caching mode will monitor the site in the background, and it can detect if there was any change in the source. If there is any difference between the cached and the live version, it will automatically refresh the cached page.
Given that generating the critical CSS sometimes needs some CPU, it provides a powerful compute API to save some resources on your server.
In short, with Swift Performance plugin you can increase WordPress performance and decrease the load time to get a quicker site.
