⚡️ Speed up method JiraDataSource.dynamic_modules_resource_register_modules_post by 20%

[codeflash-ai]

📄 20% (0.20x) speedup for JiraDataSource.dynamic_modules_resource_register_modules_post in backend/python/app/sources/external/jira/jira.py

⏱️ Runtime : 2.55 milliseconds → 2.12 milliseconds (best of 23 runs)

📝 Explanation and details

The optimized code achieves a 19% runtime improvement and 4.5% throughput increase through several targeted micro-optimizations that reduce function call overhead and unnecessary object allocations:

Key Optimizations:

1. Conditional URL Construction: The original code always called _safe_format_url() even when _path was empty (which it always is in this case). The optimization adds a branch to directly concatenate base_url + rel_path when _path is empty, avoiding the function call overhead entirely. This eliminated ~19.7% of the original execution time.

2. Conditional Dictionary Conversions: Added early-exit checks in _as_str_dict() to return empty dictionaries immediately without creating comprehensions. Since _path and _query are always empty in this workflow, this saves unnecessary iterations and temporary object creation.

3. Streamlined _safe_format_url(): Removed the _SafeDict wrapper (which appears to be undefined) and added an early return for empty params, reducing function call overhead when no formatting is needed.

4. Memory Layout Optimization: Reorganized variable initialization into a single block for better CPU cache locality and combined _body creation with the modules assignment.

Performance Impact Analysis:

The line profiler shows the most significant gains in:

• URL construction (reduced from 19.7% to 2.3% of total time)
• HTTPRequest creation (reduced from 59.1% to 23.4% of total time)
• Dictionary conversion operations through conditional short-circuiting

Test Case Suitability:

These optimizations are particularly effective for:

• High-frequency API calls (throughput tests show consistent 4.5% improvement)
• Concurrent workloads (large-scale concurrent tests benefit from reduced per-request overhead)
• Scenarios with consistent empty path/query parameters (which appears to be the common case for this Jira endpoint)

The optimizations maintain identical functionality while reducing computational overhead, making them ideal for production workloads where this method is called frequently in API request processing pipelines.
