Contention ratio of shared CPUs on App Platform

Hello,

The exact performance gains would really depend on your use case. What I would personally do is to start two Droplets, one with a shared CPU and one with a dedicated CPU, and run some tests with my specific application.

Here is some more information that might be helpful:

Dedicated CPU Droplets have guaranteed access to the full hyperthread at all times.

With shared CPU Droplets, the hyperthread allocated to the Droplet may be shared between multiple other Droplets.

When a shared CPU Droplet experiences heavier load, the hypervisor dynamically allocates more hyperthread(s) to it.

However, the amount of CPU cycles available for the hypervisor to allocate depends on the workload of the other Droplets sharing that host.

If these neighboring Droplets have high load, a Droplet could receive fractions of hyperthreads instead of dedicated access to the underlying physical processors.

In practice, this means that shared CPU Droplets can have access to full hyperthreads, but it’s not guaranteed.
