require 'benchmark/ips'

collection_size = 200000
sample_size = 10000

values = (1..collection_size).to_a.map {|x| "THIS IS A LONGER STRING THAT IS ALSO UNIQUE #{x}"}

symbol_hash = {}
string_hash = {}

values.each do |x|
symbol_hash[x.to_sym] = 1
string_hash[x] = 1
end

string_sample_array = values.sample(sample_size)
symbol_sample_array = string_sample_array.map(&:to_sym)

Benchmark.ips do |x|

x.report("string") {
string_sample_array.each do |s|
string_hash[s]
end
}

x.report("symbol") {
symbol_sample_array.each do |s|
symbol_hash[s]
end
}
