Please suggest how to fine tune the performance.
Hire an experienced Qlikview consultant. There's no howto for this where you can follow step for step instructions and arrive at a defined solution. If you've got that kind of pricey hardware you should be able to afford a consultant to help out for a couple of days and teach you what you should pay attention to in your infrastructure and qlikview documents.
Hi Gysbert ,
I have a consultant too working for the same application. Since we were facing the data discrepancy issue so we were not able to finalize incremental reload. So we have removed Pre load configurations. In term of performance how you suggest it should work with the above hardware and data size. Just want to have a view since I don't have any benchmark to compare.
