Although load time will vary largely depending on your hardware, running background services and so, you are loading from a resident table, and that usually takes some time. Did you try loading from a QVD instead if possible?
Completely forgot that loading resident table takes longer. As soon I changed it the qvd file it reduced the load time by 9 minutes. It still took a minute to generate the temp table. But that is a significant amount of time saved. Thanks Miguel!
Glad to help. Starting with version 10 QlikView increases performance loading resident tables and rendering charts because it takes advantage of the hardware multi threading technologies, so what was done by one core now it's done by several. But anyway a resident table is still in memory, and usually reading from QVD is a faster option.
