Is SambaPOS optimized to use CPUs with 4 or more physical cores? Often times 4 or more core CPUs have significantly lower base clock speeds compared to their lower core count variants.
Is it more cost effective to use CPUs with only 2 physical cores and higher base clock speed?
Net framework has extensive multi processor, multi threading support and libraries. I am sure its supported with SambaPOS but you will have to do a benchmark yourself.
All my multi terminal setups I use 4 core cpu, 8GB ram, ssd and it runs very smoothly on both server and terminals.
