    **Improved** the variables `PILOT_MAX_REQUESTS_PER_SECOND` (which rate limits the incoming requests, previously defaulted to 25.0)
    and `PILOT_PUSH_THROTTLE` (which limits the number of concurrent responses, previously defaulted to 100) to automatically scale with the
    CPU size Istiod is running on if not explicitly configured.
