I would support this part of the proposal.  I've had even more obvious example,
a CGI that generates pictures based on defined commands and a table of
such generated pictures.  Overhead of establishing connections and
launching CGI is simply unbearable (even more when you take into account
that it is something like 8 generated pictures less than 200 bytes each).

Example is on:
