Chip: Nice recap.
I'm interested in understanding the difference between passing a pointer and dereferencing the pointer during the operation versus passing a pointer, working on a local, and then doing Copy array($localTextArr_AT;t$arrayPtr_P->). Over the years, I've wondered about the performance penalty of passing by reference and, when I asked the question at the Summit, the immediate answer was that operations took 1.6 times as long. With that in mind, I'm following the Copy array approach when working with anything but trivial amounts of data. Given that you're dealing with large amounts of data, it might be interesting to see if the 1 minute elapsed time could be reduced by that change. -- Douglas von Roeder 949-336-2902 On Thu, Nov 17, 2016 at 1:29 PM, Alan Chan <[email protected]> wrote: > Isn't it fun and rewarding:-) > > Alan Chan > > 4D iNug Technical <[email protected]> writes: > >My new code imports the same 50 meg file (compiled) in just over 1 > >minute. > > ********************************************************************** > 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:[email protected] > ********************************************************************** > ********************************************************************** 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:[email protected] **********************************************************************
