Subject: How to control thread number

Hi all,

I copy the  following script from Ruby programming language(bundling
with Ruby). If the size for pages (array size) is small,thread works
very well. If the array size is big (such 2000) the thread doesn't work
at or very slow. I wonder what is the best means to control thread
number based on this script, read a small trunk of array at a time using
each_slice method?

Thanks,

Li

pages = %w( www.rubycentral.com

           )

threads = []

for page in pages
  threads << Thread.new(page) { |myPage|

    h = Net::HTTP.new(myPage, 80)
    puts "Fetching: #{myPage}"
    resp, data = h.get('/', nil )
    puts "Got #{myPage}:  #{resp.message}"
  }
end
