HI

for increase performance of application

Reducing data volume. The most common thing I have seen is people keep large amount of historical data in their applications. Maybe we should ask ourselves if it is really necessary to keep 10 years worth of data.Pre-calculating most frequently used expressions. For instance, if lots of charts are about Last Year Sales, instead of using on-the-fly calculation to dynamically figure out last year’s sales, maybe we should populate a new Last Year Sales field in the data model. Sometimes these expressions can be pre-calculated as flags;

Avoid big listboxes or tables boxes. Believe it or not, many people put listboxes or table boxes with millions of rows on the QlikView interface without know the tremendous system resources these objects consumes;

Thanks

I think your questions are a bit too generic in order to be able to give you any good answer. You will get better answers if you keep one question/topic per community thread, and also specify the context in which your question comes from. It is is a bit much to ask for an exact answer, when the question is very vague.

For example I think you know that performance tuning in general means that you improve performance of something by optimizing settings. To give you any sort of detail on such a questions you would have to specify what the performance issue is that you are trying to resolve.

For Qlik Sense I would suggest that you use the online help as reference for questions regarding features as functions.

My experience from interviews is to read up on relevant things. You will answer interview questions best if you really know what you are talking about, and that is knowledge no one can just hand to you in a sentence or two. 

I doubt that you will find anyone in the community that will take time to repeat things that already have been written. On the other hand I am sure you can find assistance in clarifying in more detail if there are details in the existing material that you do not understand or want to learn more about.

My advise to you is to not try and cheat your interview, but instead study and make it a good interview. Some of the areas you ask for can be found in links below, and then of course use QlikView and try to understand how it works.

Good Luck with your interview.
