Hi Chip,
At the end of the process that is slow after some time, i already do the
your suggestions.
Thanks

Hi Ferdindao,
I do not know what your process does. - but -
It does sound like there is an issue with memory.
Others have responded with ideas about changing cache settings, I would
follow there suggestions, too.
As I suggested, below, it is possible to create a memory leak - a
situation where 4D (your application) requests memory form 4D/system,
does stuff, finishes but does NOT return all of the requested memory to
4D/System. This is called a memory leak.
On a Mac, Safari and Firefox (windows too?) both have issues like this.
ex: open one of these programs memory usage is say 100 megs
You open 10, or 30, or 50 tabs
close all the tabs
memory usage might be 250 megs
repeat this enough times and your system slows down, or the application
crashes.
for 4D, as I said below, you need to make sure at the end of each
process (as it quits) the following items are cleared/emptied/removed
from memory; this may not be exhaustive, and if not others i'm sure
will chime in:)
(it is often best to clear these items as you finish using them, rather
then waiting until the end)
- sets
- selections
- arrays (locals are supposed to be cleared for you)
- Lists
- hierarchal lists (be sure to clear lowest level to highest)
- named selections
- and turn off Event, and Err call methods
if you have done the cache changes others suggest, and insure that all
of the above items are cleared, I would expect your slow downs to go
away.
