    > 50 is the hardware limit this can't be true, If that hardware can run Django and Phoenix, it for sure can handle orders of magnitudes more concurrent clients than 50 even before …

    Your "Concurrency" benchmark ends at 50 concurrent clients. Continue testing at C1K, C10K, C100K, C1M, C2M, etc. That's for a single node. Then try multiple nodes / cluster - C1M, …

    It doesn't matter CRUD, REST, 2PC, or middleware in general. From my PoV they're all technical solutions used to avoid deep modeling of the domain and its workflows, and instead tr…
