    🦸cape.el - Completion At Point Extensions (by minad)

    • corfu is blazingly fast. Orderless is as well. What is not always blazingly fast is your completion providing backend. You didn't mention where your slow completions are coming from. An LSP server? Dabbrev? Maybe a remote machine? Have you combined results from various backends (e.g. using cape?). Some completions backends are unavoidably slow, others are just not well optimized.

    :desert_island: corfu.el - COmpletion in Region FUnction

    • A few days ago I found an unexplained slowness when using Corfu on Emacs 29 with pgtk. I stripped my configuration to basically just Corfu, and still had a noticeable delay. Maybe it is related to your problem. https://github.com/minad/corfu/issues/307
