|---|---|---|---|
| Admin dashboard (without caching) | 1 | 20 times faster | 20 times faster |
| Normal pages （with caching） | 1 | 2,330 times faster | 2,150 times faster |
KUSANAGI 9
KUSANAGI 9 achieves more than 25,000 concurrent requests per second (HTTP) when using page cache and more than 210 concurrent requests per second (both HTTP and HTTPS) when not using page cache in a typical cloud environment (*3).
Compared to the standard LAMP environment (*2), the speedup is approximately 2,330 times faster when page cache is used, and approximately 20 times faster when page cache is not used.
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.
