Each VPS plan is provided a predetermined set of CPU and memory. As customers begin to move up our product line, we’re essentially doubling these figures and resource consumables (CDN, bandwidth, storage) for you, and consequentially the number of PHP workers able to support larger volumes of concurrent traffic.
Our NGINX caching layer works to absorb the brunt of the load for websites with high cache hit rates. When we’re talking massive amounts of simultaneous traffic, caching can fall short of delivering the appropriate level of resources your website needs to remain steady. By upgrading to the next plan in line, you’re increasing the capacity to accommodate larger waves of both cached and non-cached traffic, magnifying performance.
