I started to look at my "Call Stack" to verify activation groups
i could see one of those "GET" program was working all the time,so my SQL
in this one was not so obvious(files are huge)
I'll try to change.
Thank You very much.

What command are you using to compile the program?
If you are compiling the called programs with CRTBNDRPG, and specifying
ACTGRP(*NEW), this creates a new activataion group each time either program
is called, and this can certainly slow it down.
