Nothing changed actually.
----------------------------------------
Bug #13629: Improve performance for copying array elements
https://bugs.ruby-lang.org/issues/13629#change-65263
* Author: watson1978 (Shizuo Fujita)
* Status: Rejected
* Priority: Normal
* Assignee:
* Target version:
* ruby -v:
* Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
ary_memcpy0() has calculated the cache line size every time when copy array elements.
This patch will replace it with pre calculated value of cache line size.
Array#+ will be faster around 2%.
### Before
~~~
Array#+(other) 5.167M (賊 0.1%) i/s - 25.928M in 5.017629s
~~~
### After
~~~
Array#+(other) 5.256M (賊 0.2%) i/s - 26.410M in 5.025261s
~~~
### Test code
~~~
require 'benchmark/ips'
Benchmark.ips do |x|
x.report "Array#+(other)" do |loop|
ary1 = [1, 2, 3]
ary2 = [4, 5]
i = 0
while i < loop
ary1 + ary2
i += 1
end
end
end
~~~
