When I think of all the time doing this that I’ve wasted in my life…

Hi,
In search of a performance problem in 1 of our forms I am asking for some
advice.
I have succeeded in analyzing 10 4DDebuglog.txt files (using an Oracle DB
by the way) and have come to following :
The problem is with the execution time of the "LISTBOX INSERT COLUMN"
The performance of this command is very poor compared to other commands.
In fact, it takes about 10 times longer than every other 4D command in the
logs
The LISTBOX INSERT COLUMN command takes on average 0.0286 seconds to
complete, tested on a Intel Core i7-4710MQ 2.50GHz laptop
No big deal you could say, but for a couple of our forms it IS a big deal
We have a form with 27 listboxes on it, all dynamically build, with a total
of 477 columns
So 477 * 0.0286 seconds takes up 13.6422 seconds
This is all done in the On Load event so the user must wait terribly long
for the form to show up on the screen
My question :
Do you think this performance of LISTBOX INSERT COLUMN is acceptable /
normal behavior?
Can someone confirm this performance?
Is there something, other than putting listboxes on other pages, I can do
about this?
Thanks in advance,
Piotr
