Subject: Re: Slow because of AV?

My 2 cents.
I'm under the impression that the reason that many AVs will slow down
ruby is because they check all file open operations, to make sure they
are kosher.  This won't just slow down ruby, but any other scripting
language that involves many many files, and even compiled languages
that require many files.  There are stories floating around of people
having to do major restructuring work on applications because they
ended up crawling when AV is on.
