KUSANAGI 8
KUSANAGI 8 can handle more than 23,000 concurrent requests per second (HTTP) in a typical cloud environment (*1) when using page caching. Even when page caching is not used, such as on the administration screen, it achieves more than 200 concurrent requests per second (both HTTP and HTTPS).
Compared to the standard LAMP environment (*2), the speed is approximately 2,150 times faster when page cache is used. Even when page cache is not used, the speedup is approximately 20 times faster.
