Swoole-src: Table performance quesions

[need-sleep]

Table is able to make around 1 million reads/writes per second. I have a few questions:

1) What was the specs of the system that this benchmark came from? Was it bare metal, VM/VPS, AWS, ??
2) Was this benchmark done in PHP user-space using PHP Swoole\Table object or was it using the C/C++ api in a native application
3) How does concurrency effect table? Was this benchmark one process accessing the same table, multiple processes accessing table synchronously (such as req/reply type model which would prevent lock contention), or multiple processes accessing randomly with periodic lock contention

Thank you

I can remember I have tested _table_ with some millions of requests, as around 2.5 times faster than _IPC_ and this ahead of _redis_, vice versa, too. i7, 16GB, ThinkPad.
