[QUOTE="ara.t.howard, post: 4498775"]
your test did show symbols being faster on my (linux - 2g cpu, 2g ram) machine
too btw...

but this slightly modified version shows strings being a tiny bit faster:

harp:~ > cat a.rb
require 'benchmark'

n = 2 ** 16
string_hash, symbol_hash = {}, {}

Benchmark.bm(10) do |b|
b.report("string set"){ n.times{|x| string_hash[rand.to_s.freeze] = rand}}
end
Benchmark.bm(10) do |b|
b.report("symbol set"){ n.times{|x| symbol_hash[rand.to_s.intern] = rand}}
end

string_keys = string_hash.keys.sort_by{ rand }
symbol_keys = symbol_hash.keys.sort_by{ rand }

Benchmark.bm(10) do |b|
b.report("string get"){ string_keys.each{|k| string_hash[k]}}
end
Benchmark.bm(10) do |b|
b.report("symbol get"){ symbol_keys.each{|k| symbol_hash[k]}}
end

harp:~ > ./build/ruby-1.8.4/ruby ./a.rb
user     system      total        real
string set  0.470000   0.000000   0.470000 (  0.471459)
user     system      total        real
symbol set  0.640000   0.020000   0.660000 (  0.661556)
user     system      total        real
string get  0.100000   0.000000   0.100000 (  0.101498)
user     system      total        real
symbol get  0.080000   0.000000   0.080000 (  0.077205)

i think all we are showing here is that there aren't good reasons for one over
the other.  but that's good to i supose - since people certainly seem to have
preferences.

cheers.
