    Recall that the sorter has "clients", not "frameworks". Can you update the terminology?
    
    This is confusing for the reader. The comment here says that this parameterizes the number
of frameworks but it actually also represents the number of agents.
    
    Also, the output you showed in the Testing Done section doesn't mention how many agents
are used, which is pretty important to know.
    
    Can you also parameterize this seperately on the number of agents? The allocator benchmarks
should have some example numbers:
    
    ```      
    ::testing::Values(1000U, 5000U, 10000U, 20000U, 30000U, 50000U)
    ```
    
    For clients, let's copy the numbers from the allocator benchmarks as well?
    
    ```
    ::testing::Values(1U, 50U, 100U, 200U, 500U, 1000U))
    ```

    We should more explicitly describe what we're looking to measure. It seems to me that
you're trying to measure the time it takes to do a full sort from the dirty state?
    
    Perhaps it would be more straightforward to do this benchmark in steps:
    
    Step 1. Add S slaves. How long does this take?
    Step 2. Add C clients. How long does this take?
    Step 3. Fill the cluster with allocations. To make this simple to start with, you can
allocate each agent's resources to single client (round robin through the clients).
    Step 4. Do a full sort. How long does this take?
    
    That should be a pretty comprehensive benchmark. We can call this Sorter_BENCHMARK_Test.FullSort.

    Let's also have "disk", "ports" here to try to get closer to a real world scenario. We
don't need to do any complicated port fragmentation for now.
