Memory
Primary Memory
Part 9 Appendix
Although it is possible to run QlikView with less memory, the use of a computer with at least 1 GB for 32bit
Windows and 4 GB for 64-bit Windows is recommended.
The amount of memory you need for QlikView depends on the amount of data you load, and on the data
structure. Too little primary memory will drastically affect the performance of QlikView in a negative way.
If you notice that your computer accesses the hard disk every time you make a selection in QlikView, you
either have too many programs running, or too little primary memory.
Virtual Memory
Make sure that your swap file (the virtual memory) is large enough. The swap file should in principle be as
large as possible. However, if you have limited disk space, or a lot of primary memory, you may want a
smaller swap file or no swap file.
The system usually takes care of the swap file size dynamically. However, if you have too little free space
on the hard disk, you may get problems with your swap file getting too small. In such a case, you can fix the
size of the swap file. This is done in the Virtual memory dialog, which is accessed from the task bar:
choose Settings, Control Panel, System, Performance, Virtual Memory.
Note!
32-bit Windows sets a limit of 2 GB logical address space for any one program running (3 GB for Windows
Advanced Server). QlikView can never make use of more memory than this, regardless of the size of physical
memory in the computer. This limitation does not exist when running QlikView 64-bit edition.
Note!
Defragment the hard disk before changing the swap file settings. It usually leads to a larger contiguous free
hard disk area and thus a larger possible swap file.
A.3 Dynamic Link Libraries (dll’s) Needed
In the windows system directories of all the clients there must be a number of dll’s. They are all installed during
the installation procedure. For information on the dll’s required, see the ReadMe file in your QlikView
directory. QlikView uses Windows Installer and msi technology for installation, which ensures that the correct
versions of system dll’s are always used.
