I tried a simple test. I placed 100,000 lines of text into a custom property and into a variable. I timed how long it took to directly access a single line, 10,000 times. It took 2 ticks for the custom property, and almost no time at all for the variable.
So the custom property is slower, but still pretty fast. What really matters is other stuff. For example, in the same pair of setups, if I asked for "any line" of either the prop or the variable, the process took about 30 seconds. That function call took its sweet time. So the lesson here is to watch carefully what is a first order issue, and what is a fourth order issue.

However, arrays appear not to be the fastest way to access data and apparently in this case the removal of the counter was not enough to compensate for the addition of the arrays. I see no thText in your original script. Perhaps you need to post more code, including the part that retrieves the data from the database all the way up to and including the part where it displays the data. -- Best regards, Mark Schonewille Economy-x-Talk Consulting and Software Engineering Homepage: http://economy-x-talk.com Twitter: http://twitter.com/xtalkprogrammer KvK: 50277553 Use Color Converter to convert CMYK, RGB, RAL, XYZ, H.Lab and other colour spaces. http://www.color-converter.com Buy my new book "Programming LiveCode for the Real Beginner" http://qery.us/3fi LiveCode on Facebook: https://www.facebook.com/groups/runrev/ On 3/10/2014 16:07, Terence Heaford wrote: > Hi Mark, > > Have tried your adjustments to my script and it was a little slower than the original. > > Could that be because of the split command? > > I read the data in from an SQLite file in the return/tab delimited format. > > put revDataFromQuery(tab, return, the uDB of this stack, tSQL) into tData > > then I pass the data to the group > > set thText of group “myTable" of cd “myCard" of stack “myStack" to tData > > > I wonder if I split the data into an array and pass it directly to the group as an array if that would be quicker because there would be no need for the split to occur in the displayData routine? > > > All the best > > Terry _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
