This does depend on what you mean by "running".  The small glue apps for
the CGI can be running, as many as you can handle with your memory.  But
only one can execute with the MacPerl app simultaneously.

That's not exactly true in my experience.  What will happen is that one
will wait for the other to finish.  If you are using .cgi, you will
probably be safer, because the server will wait until the first CGI
finishes executing before attempting to execute the second.

With .acgi, this is probably where most of the problems come in, as the
server passes the request to the MacPerl app without waiting for the first
one to finish, which is probably where it hangs.


There are ways around all of this.  One is to wait for a threaded MacPerl,
which may address this problem.  That is the best.  There are other
solutions that can aid in speedier access to CGIs.

Also, someone with time and inclination might look at the source code for
the CGI Script extension and submit a patch that might fix the problem of
the hang.  This won't make anything run faster, but it will fix the hanging
problem.
