I do not have time right now to benchmark the reading, but the writing
gives some spectacular results, look at this:

517/17 > cat test-out.rb && ruby test-out.rb
# vim: sts=2 sw=2 expandtab nu tw=0:

require 'yaml'
require 'rubygems'
require 'json'
require 'benchmark'

@hash = Hash[*(1..100).map{|l| "k_%03d" % l}.zip([*1..100]).flatten]

Benchmark.bmbm do
  |bench|
  bench.report( "yaml" ) { 50.times{ @hash.to_yaml } }
  bench.report( "json" ) { 50.times{ @hash.to_json } }
end

Rehearsal ----------------------------------------
yaml   0.630000   0.030000   0.660000 (  0.748123)
json   0.020000   0.000000   0.020000 (  0.079732)
------------------------------- total: 0.680000sec

           user     system      total        real
yaml   0.590000   0.000000   0.590000 (  0.754097)
json   0.020000   0.000000   0.020000 (  0.018363)

Looks promising, n'est-ce pas?

Maybe you want to investigate that a little bit more, JSON is of
course very readable, look e.g at this:

irb(main):002:0> require 'rubygems'
=> true
irb(main):003:0> require 'json'
=> true
irb(main):004:0> {:a => [*42..84]}.to_json
=> "{\"a\":[42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,83,84]}"
