Feedback/Poor typing performance in large collections

Poor typing performance in large collections

Alex Coté·4 months ago
Released to BetaBug

Large collections (with 1000+ requests) causes poor performance when typing in most places. This affects request URL, body, parameters, headers, auth, info, and the sidebar search. It does not seem to affect the environment variable editor.

This has been tested on a 2023 Macbook Pro with an M2 Pro and 16GB of RAM.


I have made an example collection here: https://github.com/quot/yaak-large-collection

main contains the large collection, and the base-collection branch only has ~80 of the same requests. Switching between the two shows a big difference in performance.

Also tested with the cloudflare API which is ~3600 requests and it remains snappy. Let me know after you test!

Work on this is in progress in #516. It virtualizes the sidebar tree so only visible rows render, and stops reserializing the whole document on every keystroke. Thanks for putting together the repro collection.
