Hi All,
We have build a calculation view, this view have MSEG table, other calculation views and attribute views .
This view responding too long for data preview in PROD system compare to DEV system as per given screens.
I couldn't unable to find the reason for this strange behaviour. Please suggest me how can solve this issue and how to improve the performance of this view.
DEV
PROD
Thank In Advance

Hi,
This sort of topic has been discussed here quite frequently. In short: if you need to test performance of a query, get the real use scenario
Data preview 'raw data' option is the worse option for performance evaluation since this will get all the columns you have with no filtering whatsoever. Bad bad choice. See SAP Note 1894854.

Hello Kohli,
How many rows are there in MSEG table? Can you partition it?
Can you see something unusual under Performance tab of Hana Studio when you are selecting data?
Expensive statements? Others running threads, sessions, jobs? Load graphs?
You can check Runtime information of MSEG data using Catalog --> SAPDID-->Tables -->MSEG --> Context menu --> Open definiton.
On definition page there is Runtime information. What do you see on this page? All data loaded to memory?

Hi Yuksel AKCINAR,
MSEG table contain 18 Million records, it wasn't partition
After re loading the MSEG table , now I can see both DEV and PROD are responding same time and in both places the view taking long to respond more than 2 min, whereas other views for same number of records selection taking 45sec
The run time is showing as per screen
Moreover I executed in visual plan to check if there any clue but taking long to opne.
Its been 15 min still running
