⚡️ Speed up method MCPClientBase._convert_content by 6%

[codeflash-ai]

📄 6% (0.06x) speedup for MCPClientBase._convert_content in src/mistralai/extra/mcp/base.py

⏱️ Runtime : 459 microseconds → 432 microseconds (best of 71 runs)

📝 Explanation and details

The optimization achieves a 6% speedup through two key changes:

1. Operator optimization: Changed if not mcp_content.type == "text": to if mcp_content.type != "text":. The != operator is marginally faster than the not ... == construction because it avoids the additional boolean negation operation.

2. Truthiness check optimization: Modified name or self.__class__.__name__ to name if name is not None else self.__class__.__name__. This uses an explicit is not None check instead of relying on Python's truthiness evaluation, which can be slightly faster and more explicit about the intended behavior.

The line profiler results show that the conditional check (if mcp_content.type != "text":) accounts for nearly 50% of the function's runtime, making even small optimizations to this line impactful. The annotated tests demonstrate consistent performance gains across various scenarios, with the most significant improvements (6-8%) occurring in batch processing scenarios like test_many_text_contents where the optimization compounds across many iterations. The optimization is particularly effective for high-frequency method calls where these micro-optimizations accumulate to meaningful performance gains.
