Compromise almost runs twice-as-fast on **node v10** as **v4**. Kodus to node team! ### Caching **[.cache()](https://observablehq.com/@spencermountain/compromise-cache)** allows you to pre-compute a document's words and tags, to fail-fast on some match statements. If you are running many matches, especially on a large document, you may benefit from running \`.cache()\` first, but be wary of [uncovered invalidations](https://observablehq.com/@spencermountain/compromise-cache) if you are also transforming your document. #### Sweep **[.sweep()](https://observablehq.com/@spencermountain/compromise-sweep)** allows you to pre-compute a list of matches, so that no pattern will need to be checked twice, on the same document. This can greatly improve the speed of any exhaustive matches, and can be used to tag a document as well. #### Webworkers To improve performance, or move it off the main thread, you may want to [use a web-worker](https://www.html5rocks.com/en/tutorials/workers/basics/). Because you can't pass-in a function to a web-worker, annoyingly, you must load the library each time. you can see a demo of this [here](https://github.com/spencermountain/compromise/tree/master/demos/web-worker). #### Disabling POS-tagging you can turn-off the most laborious part of compromise, part-of-speech tagging, if you don't need word-categorization, by using \`compromise/one\` or calling \`nlp.tokenize()\` instead: `36:[] 32:{"id":"b36e9b460643c5f7","slug":"compromise-performance","title":"compromise-performance","thumbnail":"41675d4e9ea4826107d280ad3a94f312dfb26bfd6c551805fccabbe64a161eca","access_level":"public","create_time":"$D2018-03-14T15:25:50.548Z","update_time":"$D2023-01-19T14:20:06.047Z","view_time":null,"first_public_time":"$D2018-03-14T20:15:16.230Z","has_unpublished_edits":null,"fork":false,"stars":2,"starred":false,"owner":{"type":"team","id":"178b998367cf1e11","login":"spencermountain","name":"spencer kelly","avatar_url":"https://avatars-next.observableusercontent.com/006044842415892d25db450d275d493d3e5629ec1c2a2dfad0167421e0f026f9","tier":"starter_2024"},"version":389,"publish_version":null,"role":null,"authored":false,"authors":[{"type":"individual","id":"25825fd15d797d3f","login":"spencermountain","name":"spencer kelly","avatar_url":"https://avatars-next.observableusercontent.com/006044842415892d25db450d275d493d3e5629ec1c2a2dfad0167421e0f026f9","tier":null}],"members":[{"type":"individual","id":"25825fd15d797d3f","login":"spencermountain","name":"spencer kelly","avatar_url":"https://avatars-next.observableusercontent.com/006044842415892d25db450d275d493d3e5629ec1c2a2dfad0167421e0f026f9","tier":null,"role":"editor"}],"comments":[{"id":"8e4e0a4fd79a84eb","reply_to_id":null,"content":"The webworker example links gives a 404","create_time":"$D2023-01-19T01:53:15.170Z","update_time":null,"resolved":true,"user":{"type":"individual","id":"6cdb6324966da5d4","login":"dleeftink","name":"","avatar_url":"https://avatars-next.observableusercontent.com/3700a558b99f2f54fb2542d09667aadabaae51f24e04e47e420c844503696b0e","tier":null}},{"id":"231efa066cad9987","reply_to_id":"8e4e0a4fd79a84eb","content":"thanks!","create_time":"$D2023-01-19T14:20:17.422Z","update_time":null,"resolved":true,"user":{"type":"individual","id":"25825fd15d797d3f","login":"spencermountain","name":"spencer kelly","avatar_url":"https://avatars-next.observableusercontent.com/006044842415892d25db450d275d493d3e5629ec1c2a2dfad0167421e0f026f9","tier":null}}],"custom_thumbnail":false,"trashed":false,"lapsed":null,"subscribed":null,"forks":2,"collection":{"id":"e53dcf6ebdb6a393","slug":"nlp-compromise","title":"nlp-compromise","owner":{"id":"178b998367cf1e11","login":"spencermountain","name":"spencer kelly"}},"type":"notebook","body":{"title":"compromise-performance","cells":[{"id":0,"value":"md`# compromise-performance\n\ncompromise was built with the goal of parsing and transforming text **on keystroke**, so it is relatively quick.\n\nit is also:\n* **synchronous** - no callbacks!\n* **linear** - *O(n)* - *(10x words take 10x time)* \n\ncompromise can parse ~***one sentence per millisecond*** in a modern desktop browser.\n\nyou can time things here, by loading some large texts, and performing benchmark on them:\n`","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","output":"$undefined","database":"$undefined"},{"id":5,"value":"viewof txt= html`\n`","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","output":"$undefined","database":"$undefined"},{"id":11,"value":"{\n return html`\n\n \n\t\n\t\n \n \n\t\n\t\n \n \n\t\n\t\n \n \n\t\n\t\n \n \n\t\n \n
