Some options improve performance while others sa improves socket operation performance by 20-200% but may reduce multi-threaded scalability. Defaults to ``true``. - **enable_lwip_check_thread_safety** (*Optional*, boolean): Enable LWIP thread safety checks to detect incorrect usage of the TCP/IP stack from multiple threads. This helps catch thread safety issues when core locking is enabled.

Some options can be disabled to save flash memory without affecting typical ESPHome functionality. The performance options (defaulting to ``true``) improve socket operation performance but can be disabled if you need better
