Will other users be affected if a shared CPU droplet crashes?

'I wasn't able to find the answer through internet searches, so I apologize in advance if this question has been asked before...

When using Artillery to test a DigitalOcean shared CPU droplet, will intentionally increasing the load affect other users on the server? If the load is pushed so high that it crashes the server, will it also impact other users' shared CPU droplets?

My initial tests involve making data API requests to an Express server, but eventually I will need to make requests to React web pages.

I want to ensure I am being considerate of others sharing the server.

Answer №1

It is unlikely that the performance of other users sharing the same CPU would be affected, as the CPU is partitioned using a hypervisor. For example, if a single machine runs 8 shared CPU instances, each with 4 cores, you can apply varying levels of load to different cores without impacting the performance of others. This principle also applies on a per node basis.

While it could be argued that increased load may lead to higher heat generation (which may not be an issue in a datacenter setting) and greater memory bandwidth usage, these factors are typically managed effectively as long as the hypervisor is properly configured.
