For TruClient protocol, the script's resource consumption varies significantly with different AUTs and different sequences and steps used. Additionally, as embedded browsers are updated with versions, their consumption is changed accordingly as well. The load-generator software is multi-threaded; however, as Vusers run in separate browsers, each browser runs its own process(es).

With all this said, the suggested ideal configuration would be a machine with 32GB RAM and 8 dual core processors, to reduce bottlenecks. Even with such specs, running large number of Vusers will probably require several machines.
