Deno boosts language server performance
Briefly

The release of Deno 1.43 on May 1 marks significant improvements in the language server, particularly in auto-completion speed and memory efficiency. The Deno LSP now completes auto-completion tasks in under one second for larger projects, a substantial reduction from the previous six to eight seconds. Additionally, memory consumption issues that led to out-of-memory errors are resolved, allowing for smoother operation in demanding projects. Users can upgrade to this new version by running the deno upgrade command in their terminal.
Deno Land developers have reworked many aspects of the Deno language server, commonly referred to as Deno LSP, which provides auto-completion in the editor.
With Deno 1.43, auto-completion now takes less than one second in larger projects when it used to take six to eight seconds.
The enhancements in Deno 1.43 also address memory consumption issues, allowing projects that previously caused out-of-memory errors in the LSP to operate without issue.
Deno 1.43, introduced on May 1, can be accessed via running the deno upgrade command in a terminal.
