⚡️ Speed up method V2SocketClient._is_binary_message by 26%

[codeflash-ai]

📄 26% (0.26x) speedup for V2SocketClient._is_binary_message in src/deepgram/listen/v2/socket_client.py

⏱️ Runtime : 1.58 microsecondss → 1.25 microseconds (best of 39 runs)

📝 Explanation and details

The optimization replaces isinstance(message, (bytes, bytearray)) with direct type comparison using type(message) is bytes or type(message) is bytearray. This avoids the overhead of isinstance(), which must check inheritance hierarchies and handle tuple unpacking for multiple types.

Key changes:

• Uses type() with identity comparison (is) instead of isinstance()
• Explicitly checks each type separately rather than using a tuple
• Removes the isinstance fallback since bytes and bytearray are concrete built-in types

Why it's faster:

• type() is a direct attribute lookup, while isinstance() involves more complex logic
• Identity comparison (is) is faster than the inheritance checking isinstance() performs
• Eliminates tuple creation and iteration overhead from (bytes, bytearray)

Performance characteristics:
The 26% speedup is most effective for frequently called type-checking operations on binary data, which is common in socket communication scenarios where messages need rapid classification between text and binary formats.
