    I am programming in Xm under SCO UNIX in a 386 box with 16 Meg memory.
After I run several large programs, I use up all the memory and system
starts memory paging, which slows down system dramatically.

    I hope someone can shed some light on the following questions:

1) The size of motif programs seems abnormal huge: a compiled execute file
   as simple as "Hellow World" occupies almost 1 mega bytes. I do not know
   whether the problem is unique to SCO UNIX. Is there any way to reduce
   the size of the program? How it works at the other environments.

2) I have several huge programs each with hundreds of Widgets.
   Atter I load some of my programs, the numerous widgets created engulf
   all the system memory, and the system performance deteriorates.
   I have already tried to reuse, reconfigure the windows as much as
   possible, but I still have scores of windows and hundreds of Widgets.
   For performance sake, I create all the widgets at start up, leave
   them there, just change attributes, managed and unmanaged them according
   to user's response. Am I terribly wrong?


   Thanks in advances.
