- Comparing kafka.m5.2xlarge against kafka.m7g.2xlarge instance type
- Data Import durations and CI/CO response time do not differ significantly. The number of requests during 2 hour CI/CO with Data Import test stayed the same 287669 in m5 and 287155 in m7g MSK instance type.
- Resource utilization
- Memory utilization didn't differ a lot between two MSK clusters
- Disk consume less resources in both (idle and CICO+DI) scenarios with m7g instance type. CPU utilization 6 times bigger the same in idle state but 20% less under load with m7g instance type.
- Average DB CPU usage
- Average connection count
