Subject: Re: Looking for information on string processing performance

Thank you, Robert. That's great advice! I will keep them in mind while
learning Ruby. If files become ridiculously large, there is always
c/c++ there. But I really want to do as much work in Ruby as possible.

I tried in place replacement and the use of << in stead of +, and my
little test scripts run much faster (300% better).

Could you elaborate  on "when processing large files process them
streaming mode"? Do you mean using iterator such as
IO.foreach("testfile") { |line| ........ }
in stead of the way like
arr = IO.readlines("testfile") ? Or is there another library I should
look into?

Thanks again for your help.
