Yes, if you have enough users hitting your programs.  Or if a user double
clicks on a CGI link, the program will become activated in at least 2 RP
jobs, for example.    Programs remain active in the RP job until the HTTP
Server is shut down.  Or (as you mentioned) the RP Job is ended by the
operator.

Named activation dramatically increases CGI performance, initially.  That's
because the program remains "active" after the 1st call.  If you write
enough CGI programs, and they all become active in each of the RP jobs,
you'll eventually reach a point where named activation hinders overall
system performance.

For example, 100 CGI programs and 40 RP jobs could lead to 4000 active
program instances.

I can't think of a good reason to use any more than one named activation
group for all CGI programs.
