Issue #12180 has been updated by Shyouhei Urabe.


We looked at this issue in yesterday's developer meeting.

(As ko1 measured before,) we confirmed that ffalcon's implementation is the fastest.  Ko1 is assigned to switch to that.

----------------------------------------
Feature #12180: switch id_table.c variant
https://bugs.ruby-lang.org/issues/12180#change-62595

* Author: Yura Sokolov
* Status: Assigned
* Priority: Normal
* Assignee: Koichi Sasada
* Target version: 
----------------------------------------
Currently used variant is 'binary search in small table + hash for large tables'.
But for contemporary CPU it may be better to do linear scan for small tables.

It is already implemented in `id_table.c` and numbered as 35.

Tested with simple Redmine installation on Intel Haswell i7-4770 CPU @ 3.40GHz

- trunk:
`Requests per second:    27.79 [#/sec] (mean)`
- with switched implementation:
`Requests per second:    28.87 [#/sec] (mean)`
