有人用过cell么？

<span style="font-size: small;"><a target="_blank" href="http://rubyforge.org/frs/?group_id=2978&amp;release_id=9650">http://rubyforge.org/frs/?group_id=2978&amp;release_id=9650</a>
<br /></span>
<br /><span style="font-size: small;"> </span>
<br /><span style="font-size: small;">
<br />非常小，源代码一目了然。感觉虽然有点土，但比自己做个module的方式好一点点
<br />号称： 代替发挥component作用的controller， 这样就不需要邪恶的render_component了
<br /></span>
<br /><span style="font-size: small;">A cell acts as a lightweight controller in the sense that it will assign variables and render a view.</span>

To test out the cache miss behavior of read operations, run a program building the index (30k entries) then another program building then reading the index (30k queries), and find their diff.

Here's how to generate the test script cmd.sh

3.times do |i|
  %w[triez hash da].each do |ty|
    puts "valgrind --tool=cachegrind --cachegrind-out-file=tmp/#{ty} ruby t.rb #{ty}"
    puts "valgrind --tool=cachegrind --cachegrind-out-file=tmp/#{ty}.read ruby t.rb #{ty} read"
    puts "cg_diff tmp/#{ty} tmp/#{ty}.read > tmp/#{ty}#{i}.diff"
