✅ Corrected Payload

// Trimming log samples or using command-line diff tool for large files

💡 Explanation: Myers LCS algorithm has O(ND) time complexity. Comparing huge files in browser memory can exceed thread limits.

Common Root Causes

  • Pasting multi-megabyte log files into browser text inputs.
  • Comparing binary files instead of plain text.

Recommended Solutions

  • Truncate massive log files to the relevant lines before running browser diffs.
  • Use terminal `diff -u file1 file2` for multi-gigabyte server files.
