⚡️ Speed up method `ListComponentResponse.tags_to_list` by 31% in `src/backend/base/langflow/services/store/schema.py`
📄 ListComponentResponse.tags_to_list() in src/backend/base/langflow/services/store/schema.py
📈 Performance improved by 31% (0.31x faster)
⏱️ Runtime went down from 30.2 microseconds to 23.0 microseconds
Explanation and details
Sure! Here are a few optimizations you can make to your code for better performance.
- Avoid multiple list comprehensions inside
all()by using a single loop. - Access dictionary elements only once by storing them in variables.
Here's the optimized code.
Explanation.
- Single Loop Check: Instead of checking all tags in a list comprehension inside
all()(which needs to iterate twice), the optimized code uses a single loop. - Direct Element Access: The dictionary elements are accessed once and stored in a variable, saving dictionary access time.
- Early Exit: If a condition fails during the loop, we immediately return, avoiding unnecessary further checks.
This should enhance the performance by reducing the number of iterations and improving the readability of your code.
Correctness verification
The new optimized code was tested for correctness. The results are listed below.
