docs/data/reusables/enterprise_installation/increasing-cpus-req.md

When you increase CPU resources, {% data variables.product.company_short %} recommends adding at least 6.5 GB of memory for each vCPU (up to 16 vCPUs) that you provision for the instance. When you use more than 16 vCPUs, you don't need to add 6.5 GB of memory for each vCPU, but you should monitor your instance to ensure it has enough memory.
