DigitalOcean load spike, slowing down cms

We are experiencing load spike on our xibo cms droplet on DigitalOcean, this causes longer page loading times and halting of production.

I can see that the cpu load seems to be the bottleneck but i’m unsure if resizing to “more” vCpus would help this since I don’t know if docker xibo cms runs multithreaded or how that works, any suggestion or tips?
