performance evaluation within the trusted world

[stefvas]

I am currently working on an enclave-based application and would like to conduct a performance evaluation to ensure that the application meets the desired benchmarks. However, I am unsure about the best practices, tools, and methodologies for performing a comprehensive performance evaluation within an enclave environment.
Questions

What are the recommended tools or frameworks for conducting performance evaluations specifically within an enclave?

Which performance metrics should be prioritized in an enclave environment (e.g., CPU usage, memory overhead, I/O latency, etc.)?

Are there any specific configurations or setup steps required before initiating a performance evaluation within an enclave?

How can I accurately benchmark the performance of my enclave application against non-enclave applications?

What are the common challenges or pitfalls to be aware of when performing performance evaluations in this context?

Additional Context

Any guidance, references to documentation, or examples would be greatly appreciated.

Thank you!
