Answer 1

The most expensive + a bunch of system administrators to it!
But seriously, everything is individual, you need to look at your project and make recommendations based on the analysis

Answer 2

Processor
Frequency is affected. The number of cores does not matter
Вариант 1. cpukiller.com увеличит нагрузку на процессор
Вариант 2. VirtualBox
Команда для проверки свободной ОЗУ на linux
The SSD has no effect.
I tried to transfer from HDD to SSD, the speed did not increase at all. I myself was surprised
Я переносил систему на реальный SSD. Но можно воспользоваться и VirtualBox если на вашем компьютере есть и HDD и SSD диски. Виртуальную машину можно переместить на любой диск
