This is a CGI script, i.e., a tiny program run by a Web server to
generate a page's output. Yes, I know, there have been newer techniques
replacing CGI, but there're actually good reasons why in this case we're
still using CGI (it's a long story).
So if the CGI takes 3ms, it means we can only run 333 of them each
second, and as always, we'd prefer to get 400, or 1000 :-) So we would
like to understand what's taking the time. One of the thing we
suspected is a lot of time in the kernel, and we want to verify this
suspicion.
