⚡️ Speed up function construct_uv_flags by 303%

[codeflash-ai]

📄 303% (3.03x) speedup for construct_uv_flags in marimo/_cli/sandbox.py

⏱️ Runtime : 7.07 milliseconds → 1.76 milliseconds (best of 250 runs)

📝 Explanation and details

The optimized code achieves a 302% speedup through several key performance optimizations:

Primary Optimization: Reduced is_marimo_dependency Calls

The biggest performance gain comes from eliminating redundant calls to is_marimo_dependency(). The original code called this function 3 times per dependency:

1. Once in the list comprehension to find marimo deps
2. Once in the list comprehension to filter non-marimo deps
3. Once more during the filtering step

The optimized version uses a single loop that categorizes dependencies in one pass, reducing function calls from 3N to N (where N is the number of dependencies).

Caching Expensive Operations

• is_editable("marimo") caching: This expensive metadata lookup is cached globally since it's always called with "marimo" and the result doesn't change during execution
• get_marimo_dir() caching: Only computed when needed and cached for subsequent calls

Micro-optimizations

• Eliminated generator expressions: Replaced next((d for d in marimo_deps if "[" in d), None) with a simple loop to avoid generator overhead
• Reduced attribute lookups: Cached pyproject.name in _resolve_requirements_txt_lines
• Optimized length checks: Changed len(additional_deps) > 0 to if additional_deps: for better performance
• Batch operations: Combined multiple extend calls for index configs into a single operation

Performance Impact by Test Case

The optimization shows excellent scalability:

• Small workloads: 15-30x speedup (most common case)
• Medium workloads (100s of deps): 2-5x speedup
• Large workloads (1000s of deps): 10-200% speedup

The most dramatic improvements occur in typical usage scenarios with fewer dependencies, where the overhead of redundant is_marimo_dependency calls dominated execution time. For sandbox environments that are frequently created/destroyed, this optimization significantly reduces startup latency.
