Super slow

[ridiculous]

This is a cool gem, but it's super slow compared to alternatives. Are there plans to improve on that?

Here is a simple benchmark against memo-it and memoist

require 'benchmark/ips'
module Go
  extend Memoist
  extend self

  def go_memo_it
    memo { false }
  end

  def go_memoist
    false
  end

  memoize :go_memoist
end

Benchmark.ips do |x|
  x.warmup = 3
  x.time = 10
  x.report('memo-it') { Go.go_memo_it }
  x.report('memoist') { Go.go_memoist }
end

=begin
Warming up --------------------------------------
             memo-it    16.623k i/100ms
             memoist   127.203k i/100ms
Calculating -------------------------------------
             memo-it    185.206k (± 7.1%) i/s -      1.845M in  10.010942s
             memoist      2.252M (± 6.8%) i/s -     22.515M in  10.044946s
end

thanks for the benchmark.

due to the overhead of generating the memoization key, it will always be slower than monkeypatching ruby methods.

i don't know if the term 'super slow' is appropriate thought. it's meant for optimizing 3rd party calls like http, which are really slow, like magnitudes more slowly.

if you are looking for a hot spot code optimization, this is not for you.

Cool, thanks!
