Re: Delays while editing DDS with many/slow DB references

I believe "synchronizing resources" is saving to disk. You can't compile
until the save is done. If you're working remotely from your connection,
then the save takes longer than if you're directly attached.

Another thingy thats being done in the UI thread - what also should be
done in a background thread (i think) - is "synchronizing resources".

When i edit a member, i almost always have to wait for 1/2 seconds before
the "compile" menu option is selectable, because it's "synchronizing
resources". I don't know any resources that need to be synchronized but
it's quite irritating to always have to wait 1/2/3 seconds, before being
able to select the compile menu option.

I've found that DDS lags when you have really big data dictionary

defined.

It constantly refers to that object and ties it up.

Regularly, in RDi 9.0.1 (but also in RDi 8.5) eclipse "hangs" for half
a second, apparantly because of garbage collecting, which is
unworkable if it happens continuously.

Previously, with 8.5, the problem appears when i edit DDS (Display)
sources.
I don't have this problem when editing RPG(LE) sources.

I already tweaked the VM arguments:
-Xms256m
-Xmx1280m
-Xmnx256m
-Xscmx96m
-XX:MaxPermSize=512M
-Xss2m

Installed memory is 4GB.


With 9.0.1, the problem did not seem to surface anymore.


But, now i'm editing a simple DDS (PF) source, and it's impossible to
edit because of the constant lag. I don't know what it's doing, but a
PF DDS shouldn't be too complicated to parse (unless it constantly
scans all tables in the complete library list...).
At first there was no problem, but now, after editing 3 new, simple
DDS sources all of a sudden i have to restart RDi because it's

unworkable.

Then, after restarting RDi, i continue editing the * comments in the
PF DDS (which is only three fields), and after about 20 minutes the
same behavior again.

Back to SEU again (for DDS).
