RE: Call in ILERPG response time slow

Hello Brad,

The time to call Program A will be affected by any calls it contains to service 
programs.  The system must 
resolve the service program (to see it still exists and that the user has 
sufficient authority), must 
activate the service program (load into activation group), and verify the 
signature.  All this happens when 
Program A is called, NOT when the first routine in the service program is 
called.  If their are many service 
programs or one gigantic all-singing, all-dancing service program you will see 
a delay in the load of Program 
A -- although once it is loaded the actual calls to routines in the service 
program will be faster than 
dynamic calls.  Of course, this is more noticable on the smaller AS/400 models  
-- a 600 for instance.

Regards,
Simon Coulter.
