I think I got something wrong, were I could find some objective benchmarks and do it right guides?</P> <P>&nbsp;</P> <P>Note that I tend to use tMap heavily, could this be a problem?</P> Sat, 16 Nov 2024 09:38:21 GMT https://community.qlik.com/t5/Talend-Studio/How-could-I-improve-Talend-performance/m-p/2297641#M145059 Anonymous 2024-11-16T09:38:21Z https://community.qlik.com/t5/Talend-Studio/How-could-I-improve-Talend-performance/m-p/2297642#M145060 <P>In most cases,&nbsp;bad performances is due to, or at least linked to, database access.</P> <P>For most db, there is some components dedicated to bulkify operation and it can change your life!</P> <P>Now, it's difficult to give a complete answer as soon as we don't know which db engine(s) you are using, on which OS, how many records you try to read/write, what is the role of tMap (transformation or joins), did you compare elapsed time with direct operations (without Talend) and so on.</P> Tue, 13 Jun 2017 16:20:32 GMT https://community.qlik.com/t5/Talend-Studio/How-could-I-improve-Talend-performance/m-p/2297642#M145060 TRF 2017-06-13T16:20:32Z
