Multiple Instances of xibo CMS

I want to know how many instances of xibo i can install on my computer. My pc specifications are given below

core i3-4160 CPU 3.60GHz
8 GB of RAM
64-bit windows operating system
500 GB HDD.
Thanks in advance.

It’s hard to say as a CMS instance can have almost no impact if it has 0 Players attached to it, to alot of impact if it had 1000 Players attached to it.

Assuming the instances are relatively small, about 4-8 instances I’d say would be reasonable for a machine of that specification.
