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.

@blamb I believe the R* series of instance types generally have more memory (RAM) than the corresponding T* instance types. I'm not aware of any better "handling" of the memory.

I would assume that the recommendation to switch from T3 to R5 for network connectivity reasons is because a T3 instance has "up to 5Gbps" network performance, while an R5 server will have "up to 10Gbps" or more depending on the specific size you pick.

How about a link to the page for "baseline bandwidth"?

Your copy/paste of the official documentation and original source mention that the burstable instances have baseline bandwidth. Where can I find the actual values for baseline bandwidth for the general purpose instances? And what is the way to check or monitor Network Bandwidth credits balance. I can't seem to find CloudWatch metric for that (unlike CPU credits). Could you please help with this?

Thanks for your answer. But when we say up to 10 GBPS what would it's baseline performance?

The r instance family is memory-optimized, which you might use for in-memory databases, real-time processing of unstructured big data, or Hadoop/Spark clusters.

Hi, we have procured r5 (EC2 Instance savings plan) can this instance type be converted to r6i at later stage? Thanks
