Hi,

Since yesterday opening of a big QV Files takes much longer than the day before, with QV Desktop.

The same can be observed when scheduling the document with a task in the QMC console. Extract of the logfile is:

I have compared the QV scripts of both the fast and the long running file, they are the same.

Do you have a hint what the cause of this long-loading problem could be?

Thx a lot - Marcel

Re: Opening a QV File takes 30 minutes...

I used my working backup qvw file and have re-implemented all changes step by step. After each step I run the task in QMC and checked that it runs fine. Finally, I end with a working version that runs ok.

I could not find out what has caused the issue.

Re: Opening a QV File takes 30 minutes...

How much size is your source data being loaded?

If you have implemented a single Load from source table, Load time will increase with file size.

If Data loading is the cause of the issue, have a look at :

Types of loads in Qlikview

Re: Opening a QV File takes 30 minutes...

Initial data load is not the issue. The file size is 1680.28 Mb as you can see in the log extract.

Time consumption gets very high after Initial loading, when the file is loaded again for Distribution. See in the log extract.

If check memory consumption in Windows Task Manager, I see that memory consumption always changes between 6'123'456 MB and 6'090'232 MB when still about to open the file. But I do not know what the cause of this switching could be.
