This PR adds a benchmark intended to measure how the LSP handles larger repos, as well as its performance on a more realistic workload. The repo being benchmarked is [deco-cx/apps](https://github.com/deco-cx/apps) which has been vendored along with its dependencies. It's included as a git submodule as its fairly large. The LSP requests used in the benchmark are the actual requests sent by VSCode as I opened, modified, and navigated around a file (to simulate an actual user interaction). The main motivation is to have a more realistic benchmark that measures how we do with a large number of files and dependencies. The improvements made from 1.42 to 1.42.3 mostly improved performance with larger repos, so none of our existing benchmarks showed an improvement. Here are the results for the changes made from 1.42 to 1.42.3 (the new benchmark is the last one listed): **1.42.0** ```test Starting Deno benchmark -> Start benchmarking lsp - Simple Startup/Shutdown (10 runs, mean: 379ms) - Big Document/Several Edits (5 runs, mean: 1142ms) - Find/Replace (10 runs, mean: 51ms) - Code Lens (10 runs, mean: 443ms) - deco-cx/apps Multiple Edits + Navigation (5 runs, mean: 25121ms) <- End benchmarking lsp ``` **1.42.3** ```text Starting Deno benchmark -> Start benchmarking lsp - Simple Startup/Shutdown (10 runs, mean: 383ms) - Big Document/Several Edits (5 runs, mean: 1135ms) - Find/Replace (10 runs, mean: 55ms) - Code Lens (10 runs, mean: 440ms) - deco-cx/apps Multiple Edits + Navigation (5 runs, mean: 11675ms) <- End benchmarking lsp ``` |

Deno
Deno
(/ˈdiːnoʊ/, pronounced
dee-no) is a JavaScript, TypeScript, and WebAssembly runtime with secure
defaults and a great developer experience. It's built on V8,
Rust, and Tokio.
Learn more about the Deno runtime in the documentation.
Installation
Install the Deno runtime on your system using one of the commands below. Note that there are a number of ways to install Deno - a comprehensive list of installation options can be found here.
Shell (Mac, Linux):
curl -fsSL https://deno.land/install.sh | sh
PowerShell (Windows):
irm https://deno.land/install.ps1 | iex
Homebrew (Mac):
brew install deno
Chocolatey (Windows):
choco install deno
Build and install from source
Complete instructions for building Deno from source can be found in the manual here.
Your first Deno program
Deno can be used for many different applications, but is most commonly used to
build web servers. Create a file called server.ts and include the following
TypeScript code:
Deno.serve((_req: Request) => {
return new Response("Hello, world!");
});
Run your server with the following command:
deno run --allow-net server.ts
This should start a local web server on http://localhost:8000.
Learn more about writing and running Deno programs in the docs.
