A post circulating in developer circles argues that standard public cloud servers introduce small, unpredictable delays, and that teams running real-time workloads are moving off them onto dedicated hardware instead.
The useful part, for you, is buried in the article itself. It concedes that the delay it is worried about (around 20 milliseconds) goes completely unnoticed on an e-commerce checkout page or a company blog. That is the whole story as far as your website is concerned. The problems it describes show up in things like multiplayer game matchmaking, constant real-time data syncing, and heavy background processing that never stops. A plumbing company site, a restaurant menu, a booking form, a small online shop: none of these are doing that kind of work.
Two terms worth translating, because you will hear them from vendors. A hypervisor is software that carves one physical server into many separate virtual ones, so several businesses can share the same machine. Multi-tenant means exactly that sharing arrangement. The article's second complaint is the "noisy neighbour" problem: if another company on your physical machine runs something enormous at 2pm, your share of the hardware gets squeezed.
That one is worth knowing about, but not for the reason the article gives. If your site feels slow, the cause is almost never the server hardware. It is usually oversized images, too many plugins or tracking scripts, a database that has not been tidied in years, or a hosting plan on the cheapest possible shared tier. Those are the things to look at, in that order. Moving to dedicated hardware to fix a slow site is like buying a bigger van because the one you have is full of things you do not need.
Be a little wary if a host uses arguments like this to sell you up. "Enterprise bare metal" for a brochure site is money spent on capacity you will never touch.
What to do: nothing today. If your site genuinely feels sluggish, ask whoever maintains it to run a page speed test and tell you what the slowest single thing on the page is. That answer will be more useful than any conversation about servers.
