That's a bold claim. Migrating from NCM + clangd integration is absolutely slower.

Sorry, you're right. Tree-sitter-based syntax highlighting is buggy and slow. My point still stands.

No, you're right. Clangd does. I was commenting more on my experience, less Neovim's LSP behavior specifically.

You'll have to define slower (time to diagnostics, time to completion, are you really talking about the performance of nvim-cmp instead, etc.) preferably in a bug report with benchmarks. I've done several rounds of performance optimization since 0.5, and I haven't heard any complaints since 0.6 when I swapped out our json decoder.

I would just back up @mjlbach here, and provide my datapoint as a neovim user: I have no complaints with regards to neovim's builtin LSP client, especially with regards speed.
