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.

I've been using c6i instances in production for a couple months now, in the us-east-1 region. I replaced c5 instances. I'm currently looking at PHP performance on the c6a and we might switch to those if they perform comparably to the c6i. The c5a instances are not great for applications that are sensitive to memory latency, but do work well with more throughput oriented things like Kafka. Edit: looks like c6i is going to be the better option over c6a.
