AWS c6g vs c7g - sysbench CPU
Go back to listSysbench 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 to 1 thread up to 2x the CPU number and prime number under 64000. Here's a template of command line:
sysbench --threads=$thread --time=60 cpu --cpu-max-prime=64000 run

Observations:
- All VMs scale up linearly
- From a1 to c6g, there is boost of +15%
- +5% c6g to c7g
