Re: CGIDEV2 performance versus Net.Data

Ok.  OS/400 can efficiently manage thousands of program activations, even on
a small system.  That sounds significant.  It shouldn't surprise me.  If I
look at the call stack of a Job, or the call stack of a thread within a Job,
it shows lots of program entries.

But I still question whether OS/400 can efficiently manage thousands of CGI
program activations.  Master, help Thou my unbelief :)

It seems to me that running a CGI program in named activation group is akin
to returning to a menu from a 5250 program without ever closing it's files
or deallocating it's memory.  Will that scale as the number of interactive
Jobs increase?
