Internally at Silverstripe Ltd, we suggest Vagrant as our boilerplate dev environment. Our go-to vagrant box is silverstripeltd/dev-ssp which is meant to mimic Silverstripe Cloud platform as much as possible.
However, various staff members have different preferences. I for one, use Ubuntu on my main work station and run everything natively.
This sound like a reasonably well powered machine. It might be worthwhile seeing if it’s especially slow on specific requests. Their might be some performance issue to diagnose … some time the upside of having a slow dev environment is that you notice of your code has performance issue
