{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Pasting long json in REPL is slow","articleBody":"### Version\n\nv14.18.1\n\n### Platform\n\nLinux thinkpad-e570 5.14.13-200.fc34.x86_64 #1 SMP Mon Oct 18 12:39:31 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux\n\n### Subsystem\n\n_No response_\n\n### What steps will reproduce the bug?\n\n1. Copy a large amount of data to your clipboard¹\r\n2. Open the nodejs REPL\r\n3. Paste the data\r\n\r\n¹ The effect can be observed starting at ~2000 chars on my pc with an Intel i7-7500U (4) @ 3.500GHz).\r\nI generated the data using `cat /dev/zero | head -c 2000 | tr \"\\0\" 0 | wl-copy`\n\n### How often does it reproduce? Is there a required condition?\n\nIt is consistent and becomes more noticeable with a larger clipboard content\n\n### What is the expected behavior?\n\nThe pasting should happen instantaneous\r\n\r\nhttps://user-images.githubusercontent.com/24257556/139062239-9ba8ee71-233d-4d88-bc56-fe3387f85588.mp4\n\n### What do you see instead?\n\nOne can see how the content trickles in bit by bit\r\n\r\nhttps://user-images.githubusercontent.com/24257556/139062293-7f86da74-4931-47ca-9ada-0db24e605d4a.mp4\n\n### Additional information\n\nI am using Gnome Terminal but can observe the same behaviour in other terminals like Alacritty. The cpu utilization when pasting goes up to 100%. Other REPLs like python do not show the same behaviour.\r\n\r\n","author":{"url":"https://github.com/septatrix","@type":"Person","name":"septatrix"},"datePublished":"2021-10-27T12:06:38.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":12},"url":"https://github.com/40626/node/issues/40626"}
