09:00 PM Ruby Feature #16851: Ruby hashing algorithm could be improved using Tabulation Hashing
- @byroot
> I'd suggest running the hash related benchmarks included in ruby's repo: https://github.com/ruby/ruby/tree/master/benchmark
For most of the benchmarks, this changes doesn't make much of a different because they are either too...

- That looks good to me :+1: I may add String as well (such as Integer and String).

- From [Ruby 2.7 Object class documentation](https://ruby-doc.org/core-2.7.0/Object.html#method-i-hash):
>The hash value is used along with eql? by the Hash class to determine if two objects reference the same hash key.
From this I exp... -
- I have implemented Linear Probing and Simple tabulation in Ruby: https://github.com/Ana06/ruby/compare/master...Ana06:tabulation
I tested it using the following code:

The file ``test.rb`` looks like:
```ruby
require 'benchmark'
$N = 100000
class Ana
end

- Consider the following code:
``` ruby
h = {}
ObjectSpace.count_objects(h)
puts "Counts: #{ h[:T_CLASS] }, #{ h[:T_ICLASS] }"
objects = []
classes = []
ObjectSpace.each_object(Object){|x| objects << x}
ObjectSpace.each_object(...
