Conclusion

GIVES BENCHMARK APPROX 25,000 / SECOND / CORE 2, REAL PRACTICAL VALUES TESTED BY SNIPPETBUCKET TECHNOLOGIES.
GIVES BENCHMARK APPROX 1214440 / SECOND / CORE 9, GIVEN OFFICIAL Japranto.

YES. ACCEPTABLE WITH 9 CORE CPU WITH HIGH EXPENSIVE VPS PLAN.

AS WELL PYTHON FRAMEWORK-MEINHELD ALSO EXCELLENT PERFORMANCE.

Note: All tested with normal “Hello World”, no any database, no any logic, no such any processing.
So when any real world project implemented in that case benchmark speed may reduce.
Because of other processing power may consume by CPU, So with high CPU power with number of more cores and complex logic and complex architecture may get better result.

Additionally benchmark not tested from remote IP, just localhost base. So in real world it may varying a lot.

Official:Note when test happen.
These results were obtained on an AWS c4.2xlarge instance that had 8 VCPUs, launched in São Paulo region with default shared tenancy and HVM virtualization and magnetic storage. The machine was running Ubuntu 16.04.1 LTS (Xenial Xerus) with the Linux 4.4.0–53-generic x86_64 kernel. The OS was reporting Xeon® CPU E5–2666 v3 @ 2.90GHz CPU. I used Python 3.6, which I freshly compiled from its source code.
