Our company tested the small machine when it was moved down , I don't know the specific process , The final conclusion is , If it is AP perhaps web From small machine to x86, Configuration comparison 1：2, If it is db, Configuration comparison 1：3, That is to say, if you are on a small machine db yes 16c/32G, that x86 Virtual machine is 48c、96G, Basically, you have to use x86 It's a physical machine .
