Cloud Mercato tested CPU performance using a range of encryption speed tests:
Cloud Mercato's tested the I/O performance of this instance using a 100GB General Purpose SSD. Below are the results:
I/O rate testing is conducted with local and block storages attached to the instance. Cloud Mercato uses the well-known open-source tool FIO. To express IOPS the following parametersare used: 4K block, random access, no filesystem (except for write access with root volume and avoidance of cache and buffer.

For general scenarios that are performance-insensitive, users can consider using ARM architecture models, which offer greater cost-effectiveness.

This is our new guest from February 2023 powered by AWS Graviton3 processors. AWS claims it delivers up to 25% better performance over Graviton2-based instances. We will find out if it is true or not for ClickHouse soon.

Hi - Can you please send us a screen shot for db.m7g.large, it is advertised as "8 vCPUs, 4 GiB RAM" . db.m6g.large and m6g.large are if same size when compared.

When configuring an RDS instance with the type db.m7g.large, it is advertised as "8 vCPUs, 4 GiB RAM". In EC2, the equivalent instance type has 2 vCPUs and 8 GiB RAM. The same is true for the previous gen db.m6g.large. Is this difference intentional?

db.m6g.large and m6g.large are if same size when compared.
