Just came across this piece of news which suggests that the Ubuntu Ruby
packages might be up to twice as slow as freshly built Ruby

This is just one guys benchmark but I thought it might be of interest.
Here are is the main quote:
"The really big, flashing warning though is what happens when you install Ruby
through apt-get. Compiling from source gives you double the speed, according
to these tests. I expected a 10/20% increase, not 100%. The gist of it is
that prepackaged Ruby is compiled using the option enable-pthreads and there
is the whole issue of shared vs static libraries. But whatever the reason,
this is a significant difference."
