The CPU throttling of the lower memory settings is often easily visible in a user-facing request, even simple requests just doing some DB IO. I rarely use less than 1024mb for anything
edit: the BBC review is horrifying:
> The page takes around 500ms to render and be delivered to the audience. In that timeframe we invoke around 30 functions. Around 150ms is spent running React to render the content to HTML
> we aim to personalise almost every page in some way — making it relevant for every user on every request
Good luck making perf numbers with all those cold cached personalized pages
