@ankittk A few minor changes that I found:
In docs/BENCHMARK_ANALYSIS_REPORT.md some of it reads more like "tasks" rather then just a report such as:

Optimization Opportunities

    Pool io.Pipe buffers - biggest impact (92% of memory)
    Lazy MetadataBus creation - only when used
    Reuse Flow instances - avoid setup overhead

I also found in the README.md in the updated performance section this needs to be reworded:

AI Overhead     <0.02% at 100ms latency

This makes sounds like AI is < 0.02% of the run time. It should probably instead say something like:

Framework Overhead     <0.02% at 100ms AI latency

I'll continue to look for more issues, but this is a good start we can fix any more issues in the docs & readme in future pull requests.
