Comment 4 for bug 307462

I provided a link to a benchmark.

The way to reproduce this issue is to run
sudo apt-get install ruby
ruby benchmark.rb

Compare the results with a compiled version of ruby:

wget ftp://ftp.ruby-lang.org/pub/ruby/stable-snapshot.tar.gz
tar zxvf stable-snapshot.tar.gz
cd stable-snapshot
./configure
make
sudo make install

ruby benchmark.rb

As in the benchmark link I provided, you will see that the compiled version of ruby is much faster.
