Performance Discrepancy Analysis: Lichess Browser Stockfish vs Local Setup
By

The kind of bagel you'd toss to the pigeons.
Summary
A user is investigating performance discrepancies between Lichess's browser-based Stockfish analysis and their local Stockfish setup. They observe that Lichess reports higher nodes per second (1 MN/s vs 600 kN/s) but takes significantly longer to reach depth 30 (2:30 vs 53 seconds). The user notes that Lichess appears more "active" with frequent evaluation updates and seeks to understand these contradictory performance metrics.
Key quotes
· 4 pulledOn Lichess (browser-based analysis), Stockfish reports close to 1 MN/s on my Redmi Note 14 Pro.
However, when I run Stockfish locally via a Python program using the native executable, I only see around 600 kN/s.
What's confusing is that despite the higher reported speed, Lichess takes about 2:30 to reach depth 30, while my local setup reaches depth 30 in about 53 seconds, even though it reports a lower N/s.
Lichess also appears much more 'active' in terms of frequent evaluation updates.
