I wanted to share a situation with you and maybe few of you also have the same question I am going to ask.
Below screenshots are form our production server where you can see that I am unable to select the xLarge environment because of less physical cores available on the host.
In the second screenshot you can see that the maxim cpu utilization was never above 50%.
This is a physical box with 192GB memory and 16 physical cores. Now my question is that why do we need 24 physical cores even 16 cores are not utilized 100%?

I think in a case where you needed to expand your Dynatrace server size to Xlarge your CPU utilization would be very high and there the additional cores would be needed. Right now, I assume you are using the Large server size and your Dynatrace server is handling the current processing very well. In a case where you needed to increase the server size, you would see that the current number of cores, as well as the clock speed, was to low for all the transactions that you wanted to process.
So basically, you don't need the extra large size right now and that is why it seems weird to require so many CPU cores. If your server were in a situation where it needed to be increased then the utilization would be much higher and the additional cores would make more sense.
Hope that helps,
