⚡️ Speed up method V1SocketClient._process_message by 36%

[codeflash-ai]

📄 36% (0.36x) speedup for V1SocketClient._process_message in src/deepgram/speak/v1/socket_client.py

⏱️ Runtime : 2.67 microseconds → 1.97 microsecondss (best of 57 runs)

📝 Explanation and details

The optimized code achieves a 35% speedup through two key micro-optimizations that reduce function call overhead in the hot path:

1. Direct Type Checking: Replaced isinstance(message, (bytes, bytearray)) with type(message) in (bytes, bytearray). The isinstance() check traverses the Method Resolution Order (MRO) to handle inheritance, while type() performs a direct type comparison. Since the WebSocket protocol only sends exact bytes or bytearray objects (not subclasses), this optimization is safe and faster.

2. Eliminated Trivial Function Call: Removed the call to _handle_binary_message() for binary messages, since it simply returns the input unchanged (return message). The optimized version directly assigns processed = raw_message, eliminating unnecessary function call overhead.

Performance Impact: The line profiler shows the original _process_message took 30.8 microseconds total, while the optimized version takes only 3.2 microseconds - primarily because the expensive isinstance() check (15.6 μs) and function call overhead (5.4 μs) were eliminated.

Best Use Cases: This optimization is most effective for high-throughput WebSocket scenarios processing many binary audio chunks, where these micro-optimizations compound. For applications with mixed JSON/binary traffic, the speedup will be proportional to the binary message frequency.

The changes also added @staticmethod decorators to helper methods, clarifying their stateless nature and providing minor memory benefits during frequent instantiation.
