Notes performance tuning

by Volker Weber


You notice an increase in the time it takes to open a form containing several subforms, when some of these subforms load script libraries.


It was found that adding the LotusScript "Print" statement to the 'Initialize' event of each of the subforms resulted in a return to normal performance levels.

That's actually old wisdom.
If there is a lot of lotusscript in forms and subforms you need something in the initialize event.
runfaster = true
would also do!
I realized if the globals in the form doesn't contain LS but only the form level than the speed problem doesn't occur.

The correct workaround is to simply add some comment in EVERY form and Subform you load - so probably best to ALL of them. There is no correlation between big code in a (sub)form, small code or no code in it - simply some code has to be there and a comment is all you need. For myself I decided to add the line
' do not remove this comment
into every form or Subform into the Globals Options section.

Adding useless code all over the show makes it run faster? You guys kidding? When I was younger, we used to optimize and remove code to make software perform better...

Oh, I get it; it is a joke. IBM just wants to sell more metal. :-)

That stuff is only needed if you have code in your main forms global section in the first place. If you only have code in the forms part -- but not in globals it has no effect.
I guess it is a question of the runtime looking for the LS object in the subform and being very fast if one is there and being slow when not found. But I agree with Jan --- it's weird.

Nope it is not the print Statement that fixes this. It is the compile that comes after you saved the subform.
And if you do a recompile all lotus script at any time later again this ugly beast will raise its head again.

One brilliant guy working for pavone found out what happened and why.
