Folks, this game like Ark benefits far more from high frequency single thread performance than just having a bunch of cores. Yes, I give about 4-5GB of memory/ram to each grid, but having a newer generation CPU with HIGH single thread performance will take you much further in keeping your server fps high across your grids. Old first or second gen X series server cpus are pretty horrible single thread performance compared to modern (last 3 years) cpus out there. For my 10x10 and 7x7 with 300+ players I would MUCH prefer half the cores with higher single thread performance on a box than a couple dozen slower cpus. Later gen i7's are great, but there are some pretty cheap server 6 or 8 core CPUs out there which will give you a bit more bang for the $$ IMO. Google CPU Benchmarks and look at the single thread performance of the cpu you're looking to use and compare. My rule of thumb is nothing less than 1500 rating then make sure each grid has 1-2 cores here: https://www.cpubenchmark.net/singleThread.html
