Do the simple test. Just assign an empty trace function via the
set_trace_function method and measure the performance. It depends so
much from your code base that there is no answer to the question.

If you parse a larger XML document with rexml, rubies pure XML parser,
this is about 60x slower, now add a few breakpoints and it is even
going worse.

Heavy regexpr based code may be only 3-5 times slower as most of the is
spend in C code.
