RAM = (RAMuser × No. users) + RAMinitial
RAM〗initial = QVWsizedisk × FileSizeMultiplier; this is the initial RAM footprint for any application
RAM〗user =〖RAMinitial × userRAMratio; this is the RAM each incremental user consumes
QVWsizedisk = SourceData × (1 - CompressionRatio); this is the size, on disk, of a
userRAMratio: range between 1%–10%
FileSizeMultiplier: range between 2–10
CompressionRatio: range between 20%–90%
"For example: A 1GB .qvw document uses around 4GB in RAM for the first user (based on a multiplier of 4x to establish the initial RAM footprint based on file size). This multiplier is normally between 2x and 10x. User number two may increase this by around 10% as their calculations get cached resulting in a required RAM footprint of 4.4GB. User number 3 requires a further 10%, increasing the footprint to 4.8GB, and so on...."
