Is there a required condition?\n\nAt all times\n\n### What is the expected behavior?\n\nMemory usage does not grow significantly.\n\n### What do you see instead?\n\nMemory usage (precisely `arrayBuffers` section) grows by a few orders of magnitude. It seems to be correlated with the file size.\n\n### Additional information\n\n_No response_","author":{"url":"https://github.com/Dzieni","@type":"Person","name":"Dzieni"},"datePublished":"2023-01-25T11:30:30.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":24},"url":"https://github.com/46347/node/issues/46347"}
