topic What is more time and memory eficient? in QlikView https://community.qlik.com/t5/QlikView/What-is-more-time-and-memory-eficient/m-p/144524#M505713 <HTML><HEAD></HEAD><BODY><P>While I suspect it is better to refer to column(3), I don't know for sure. What should tell you for sure is sheet properties -&gt; objects -&gt; calc time. Try it both ways and see if there is any noticeable difference in calc time. For memory usage, I doubt there is any noticeable difference. You could check the size of the file and also the memory usage in task manager (processes -&gt; mem usage -&gt; Qv.exe). I'd bring up a fresh copy of QlikView each time. I'm not convinced there aren't memory leaks.</P></BODY></HTML> Wed, 20 May 2009 23:04:37 GMT johnw 2009-05-20T23:04:37Z What is more time and memory eficient? https://community.qlik.com/t5/QlikView/What-is-more-time-and-memory-eficient/m-p/144523#M505712 <HTML><HEAD></HEAD><BODY><P>In a straight table I have one column that is dependable on other, is it better to use the whole expression, for exp A*(B+C) or instead use column, which is already B+C, so A*column(3)?</P></BODY></HTML> Wed, 20 May 2009 14:36:14 GMT https://community.qlik.com/t5/QlikView/What-is-more-time-and-memory-eficient/m-p/144523#M505712 2009-05-20T14:36:14Z What is more time and memory eficient? https://community.qlik.com/t5/QlikView/What-is-more-time-and-memory-eficient/m-p/144524#M505713 <HTML><HEAD></HEAD><BODY><P>While I suspect it is better to refer to column(3), I don't know for sure.
