At Kinsta, we don’t constrain each site or container to just 1 or 2 CPUs and 1 or 2 GB of RAM. Instead, we allow our virtual machines to allocate CPU and RAM to each site as-needed to respond to surges in traffic and other activity on the site.
At Kinsta, we autoscale CPU and RAM to each site container.
Keep in mind that CPU and RAM aren’t the only constraints a WordPress website can come up against. With CPU and RAM removed from the equation, two other factors to keep in mind are the number of PHP workers your site requires and the performance of your website’s database.
When you combine auto-scaling with the fact that page caching is baked in here at Kinsta, sites that make good use of our caching have the ability to successfully serve an exceptional level of traffic on any of our hosting plans.
