⚡️ Speed up function parse_log_django by 171%

[codeflash-ai]

📄 171% (1.71x) speedup for parse_log_django in evaluation/benchmarks/testgeneval/log_parsers.py

⏱️ Runtime : 3.49 milliseconds → 1.29 millisecond (best of 984 runs)

📝 Explanation and details

Key Optimizations.

1. Pre-compilation of Regular Expressions: Repeated compilation of the same regex in every iteration can be avoided by pre-compiling them outside the main loop. This will save time.
2. Efficient Suffix Checking: Using endswith with a tuple of suffixes allows for faster checking and has been maintained, switching to a logical OR for clarity.
3. Reduce Redundant Operations: continue statements remove the need for additional checks when a match is found and processed.
4. Use of match Object Directly: In the multiline log pattern handling, directly using match object methods instead of unnecessary additional operations.
