WordPress admins are familiar with many caching plugins, free or paid. Some do give good results, and some are decent ones. However, one common attribute in almost all plugins is the presence of numerous configuration screens. Even a seasoned WordPress admin finds it difficult to fully set up all options of the plugin. In addition, for a non-tech person setting a paging plugin can be a daunting task.
Konstantin Kovshenin, a WordPress Core Contributor who is already working on Sail (a free CLI tool to install and manage WordPress on Digital Ocean Cloud), comes with a brand new page caching plugin “Surge.” However, unlike its counterparts, the Surge plugin does not have screens; it doesn’t even have the first screen. No configuration screen at all.
The plugin’s author claims that this gives the desired result with any well-configured hosting platform. There is no button to purge cache; it automatically gets clear on every page/post update.
Plugin author claims that Surge can handle 1000 to 2500 requests/second at 100 concurrent on a single core virtual server with only 1 GB of memory.
