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 ********************************************************************** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: http://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **********************************************************************
