jruby-1.0.0RC1を使ってみる(2)

この前、サンプルが動かないとかモサーリしてるとか書いたけど、ビルドがうまくできてないだけだった・・すいません。

あらためてJDK1.5.0_11とant1.7.0でビルド。
おかげさまでサンプルも動くようになりました。

でもよー・・

おそいよ・・？？

定番の郵便番号CSVパースを・・（KEN_ALL_1000.CSVは全国版の上位1000行）

bird:# cat ken.rb
require "rubygems"
require "faster_csv"

n = 0
FasterCSV.foreach(ARGV.shift) do |row|
  n += 1
end

puts n

なんとエラー！
おっと、そういえばjrubyの方は別途jrubyのgemでfastercsvをインスコしたんです。
rubyとjrubyのgemは別々と・・

とりあえず行数だけカウントしてみる・・（KEN_ALL_3.CSVは全国版の3倍）

bird:# cat cnt.rb
n = 0
ARGF.each do |row|
  n += 1
end

puts n

やっぱりJavaVMの立ち上がりがおそいのか・・
