Nice an automatically generated typo.

Is there a specific kind of performance (metric) in mind? latency vs
throughput? Or does it not matter

In the generic non-functional requirements, the requirements text is in natural language. So, you can write whatever you want.

This patch introduces a specialization for performance requirements which are expressed in limits of a sample set of some measured runtime of an operation.

text: |
  When a partition has exactly ${../val/performance:/params/buffer-count} free
  buffers, the ${.:limit-kind} runtime of exactly
  ${../val/performance:/params/sample-count} successful calls to
  ${../if/get-buffer:/name} in the ${.:/environment} shall be
  ${.:limit-condition}.

In this item, the corresponding test code is also included.

test-body:
  brief: |
    Get a buffer.
  code: |
    ctx->status = rtems_partition_get_buffer( ctx->part_many, &ctx->buffer );
