[ruby-core:65745] [ruby-trunk - Feature #10341] [Open] Fiber switch performance improvements

Issue #10341 has been updated by Koichi Sasada.
Status changed from Closed to Open
on mswin32, the following simple script doesn't work.
```ruby
p Fiber.new{
100
}.resume
```
```

Feature #10341: Fiber switch performance improvements
https://bugs.ruby-lang.org/issues/10341#change-49481
* Author: Knut Franke
* Status: Open
* Priority: Normal
* Assignee:=20
* Category:=20
* Target version:=20
----------------------------------------
The attached patches increase performance of switches between Fibers by ~17=
% on my test system (Linux, gcc 4.8.2).
Patches 1-3 are purely cosmetic, but included here because submitting them =
separately would cause conflicts between the patch sets. If these are rejec=
ted, I can prepare stand-alone versions of 4/5.
Patch 4 yields the most significant performance increase (~12%). The benefi=
t of patch 5 is lower, and it's a larger change; so this one could optional=
ly be omitted.
~~~
require 'benchmark'
fib =3D Fiber.new do
loop { Fiber.yield }
end
Benchmark.bm do |bm|
3.times do
results << bm.report { 10_000_000.times { fib.resume } }
end
avg =3D results.inject(:+) / results.size
[avg]
end
~~~
Raw benchmarking results:
~~~
trunk@47827 - 7.59s
patch 4 - 6.59s (87% of trunk)
patch 4+5 - 6.33s (83% of trunk)
~~~
