⚡️ Speed up method MistralJobs.create by 29%

[codeflash-ai]

📄 29% (0.29x) speedup for MistralJobs.create in src/mistralai/mistral_jobs.py

⏱️ Runtime : 201 microseconds → 156 microseconds (best of 23 runs)

📝 Explanation and details

The optimization primarily targets the URL template substitution bottleneck in the _get_url method, which was consuming 95.4% of execution time in the original code.

Key optimizations:

1. Replaced utils.template_url() with str.format(): The original implementation used multiple str.replace() calls to substitute URL variables, which is O(n*m) where n is the number of variables and m is the string length. The optimized version uses Python's built-in str.format() method, which performs all substitutions in a single pass and is significantly faster.

2. Cached attribute lookups: Added local variables like sdk_configuration = self.sdk_configuration to avoid repeated attribute lookups in hot paths, reducing Python's attribute resolution overhead.

3. Safer dict access: Changed self.sdk_configuration.__dict__["_hooks"] to self.sdk_configuration.__dict__.get("_hooks") to use the more efficient .get() method.

Performance impact: The _get_url method's execution time dropped from 1.73ms to 0.099ms (94% reduction), transforming it from the primary bottleneck to a minor component. This optimization is particularly effective for workloads with frequent URL construction, as demonstrated by the test cases showing 27-32% improvements across various parameter combinations.

The optimizations maintain full behavioral compatibility while leveraging Python's native string formatting capabilities for substantial performance gains.
