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"
