What is KUSANAGI?

Developed by Prime Strategy, KUSANAGI is an ultra-fast, open source virtual machine that allows CMS to run at world class speeds. It brings WordPress execution time to under four milliseconds, and enables 1,000 requests/second, even without page caching. With page caching, this increases to over 60,000 requests/second (both cases 4vCPU maximum performance).

As of July 2019, KUSANAGI is available in 26 countries and 198 regions, on 28 major platforms internationally, and has had a cumulative 30,000 deployments thus far.
