State of the art of European IaaS Compute - Q2 2022 - sysbench CPU

Go back to list

Filter:


Sysbench CPU is an open source micro benchmark tool. Its job is to find the highest number of prime number during a certain amount of time. This test outputs a rate comparable across our different VMs and being a simple operation, it doesn't involve thread cooperation nor intensive RAM usage.

Our testing configuration use a number of thread equal to the CPU number and prime number under 64000. Here's a template of command line:

sysbench --threads=$cpu_number --time=60 cpu --cpu-max-prime=64000 run

A good modern CPU is able to produce around 120 numbers per seconds and remain 80-90% of its strength when scaling up to 16 threads

Cloud Mercato's assertions

  • With +100% of the other competitors, Scaleway and Vultr processors seem to be particularly adapted to this kind workload
  • This benchmark also highlights the CPU power of Oracle and Hetzner
  • The lead of next crowd is constitued by Kamatera and the latest AWS's AMDs.
