RAM Calculation in QV Scalability

Mon, 26 Jan 2026 18:19:17 GMT

Hi All,

I have gone through the QlikView Scalability Overview document. It is very interesting.

RAM Calculation in the documnet is given below :

RAM = (RAMuser × No. users) + RAMinitial

Where

RAMinitial = QVWsizedisk × FileSizeMultiplier; this is the initial RAM footprint for any application

RAMuser = RAMinitial × userRAMratio; this is the RAM each incremental user consumes

QVWsizedisk = SourceData × (1 - CompressionRatio); this is the size, on disk, of a QlikView file

Assumptions:

userRAMratio: range between 1%–10%

FileSizeMultiplier: range between 2–10

CompressionRatio: range between 20%–90%

I would like to what is meant by "userRAMratio" & "FileSizeMultiplier" in the RAM Calculation???

PFA RAM calculation as well.

Thank you

Hi All,

I got answer from QlikView Architecture and System Resource Usage

It is as follows

FileSizeMultiplier is the RAM Usage of Single QlikView Application. Ex: 1GB of QlikView Application will take 4 GB of RAM.

userRAMratio is the RAM Usage of additional Users after the first User.

Ashok
