A QVD file is just a file, and the data is getting dumped straight to memory (assuming it's an optimized load). Each read will take up separate resources but there shouldn't be any issue past that. Depending on your setup, the biggest limiting factor may be I/O, network, or CPU, with memory being whatever the app will be using to store the QVD's data, times the number of apps.

Hi, 

AFAIK, Qlik will create a single thread by task, then CPU and RAM will be consumed by each tasks.
