Subject: PStore vs. YAML::Store



is there anything that can be done to improve this?  i'd like to use yaml for
this project but...

~ > cat test.rb 
require 'yaml/store'
require 'pstore'

def time label
  a = Time.now
  ret = yield
  b = Time.now
  puts "#{ label } @ #{ b.to_f - a.to_f }"
  ret
end

obj = Array.new(65536).map!{{'time'=>Time.now,'rand'=>rand}} 
pstore = PStore.new 'pstore.db'
yamlstore = YAML::Store.new 'yaml.db'

time("pstore dump time") do
  pstore.transaction{|db| db['obj'] = obj}
end

time("pstore load time") do
  o = pstore.transaction{|db| db['obj']}
end

time("yamlstore dump time") do
  yamlstore.transaction{|db| db['obj'] = obj}
end

time("yamlstore load time") do
  o = yamlstore.transaction{|db| db['obj']}
end


File.unlink 'pstore.db'
File.unlink 'yaml.db'


~ > ruby test.rb
pstore dump time @ 0.988970994949341
pstore load time @ 1.86728405952454
yamlstore dump time @ 42.3903992176056
yamlstore load time @ 47.6173989772797


ouch!
