Optimized extract_data in Main.py by caching self.get_username() before iterating over messages.

What:

  • Introduced cached_username variable in extract_data.
  • Replaced self.get_username() calls inside the loops with cached_username.

Why:

  • The username does not change during message processing.
  • Calling get_username() repeatedly (which involves string checks and attribute access) inside the loop for every message (potentially tens of thousands) adds unnecessary overhead.

Measured Improvement:

  • Baseline: 0.1856 seconds per iteration (50k messages).
  • Optimized: 0.1768 seconds per iteration (50k messages).
  • Improvement: ~4.7% speedup.
  • Correctness verified: Total messages and sent messages counts remained accurate.

Hoisted the get_username() call out of the message processing loops in extract_data to improve performance. The username is invariant during the loop execution, so repeated method calls were unnecessary overhead.

Benchmark showed ~4.7% improvement in processing speed (0.1856s -> 0.1768s per 50k messages iteration).
