At Kinsta, our unique container architecture allows sites to scale CPU and RAM usage without any limitations on clock speed or CPU execution time. Even though CPU and RAM are important factors in determining performance, they 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. If you find yourself in a situation where your site needs additional PHP workers, you can scale up your Kinsta plan with zero downtime.
When you combine our scalable cloud hosting 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 WordPress hosting plans.
