Web server performance

["Scott Adams" <as400jockey@xxxxxxxxxxx>]

I have a 170-2189 with 128MB memory.  I've been playing with the HTTP server 
stuff.

The performance on HTML based stuff, either in IFS directories or in source 
files is pretty good.  The problem is with performance of RPG programs.  I 
have one program that does the following:

   -  calls QCMDEXC to change the lib list
   -  calls several other RPG programs to create the various sections of the 
screen - top bar, left and right bar, bottom bar, etc
   -  calls another RPG program to create a random number

This collection of stuff takes about 5 seconds before any HTML starts coming 
back to the client.  Once that starts, the screen appears very quickly.  The 
first program is about 180K (optimized) and all the other little programs 
tip the scales at about 40K each.

In short, this performance is not great.  Does anyone have recommendations 
as to how to speed things up?  Could my problems be caused by any of the 
following:

- insufficient memory (there's nothing else going on with the machine) and 
it's hard to determine from WRKSYSSTS if there's too much paging going on
- calling QCMDEXC from inside RPG
- calling other RPG programs from within this RPG program

How do I find out where the bottleneck is?

Thanks in advance for any help.
