The same issue in two different places - doing blocking FS work in an
async task, limiting the amount of work that happens concurrently.
- When setting up node_modules, where we try to set up entries
concurrently but were blocking other tasks from actually running.
- When loading package info from the npm registry file cache, loading
and deserializing is expensive and prevents concurrency. This was
especially noticeable when loading an npm resolution snapshot from a
lockfile (`snapshot_from_lockfile` in `deno_npm`).
Installing deps in `deno-docs`:
```
❯ hyperfine -i -p 'rm -rf node_modules/' '../d7/deno-main i' '../d7/target/release/deno i'
Benchmark 1: ../d7/deno-main i
Time (mean ± σ): 2.193 s ± 0.027 s [User: 0.589 s, System: 1.033 s]
Range (min … max): 2.151 s … 2.242 s 10 runs
Benchmark 2: ../d7/target/release/deno i
Time (mean ± σ): 1.597 s ± 0.021 s [User: 0.977 s, System: 1.337 s]
Range (min … max): 1.550 s … 1.627 s 10 runs
Summary
../d7/target/release/deno i ran
1.37 ± 0.02 times faster than ../d7/deno-main i
```
Caching `npm:@11ty/eleventy`:
```
❯ hyperfine -i -p 'rm -rf node_modules/' --warmup 5 '../../d7/deno-main cache npm:@11ty/eleventy' '../../d7/target/release/deno cache npm:@11ty/eleventy'
Benchmark 1: ../../d7/deno-main cache npm:@11ty/eleventy
Time (mean ± σ): 129.9 ms ± 2.2 ms [User: 27.5 ms, System: 101.3 ms]
Range (min … max): 127.5 ms … 135.8 ms 10 runs
Benchmark 2: ../../d7/target/release/deno cache npm:@11ty/eleventy
Time (mean ± σ): 100.6 ms ± 1.3 ms [User: 38.8 ms, System: 233.8 ms]
Range (min … max): 99.3 ms … 103.2 ms 10 runs
Summary
../../d7/target/release/deno cache npm:@11ty/eleventy ran
1.29 ± 0.03 times faster than ../../d7/deno-main cache npm:@11ty/eleventy
```

Deno CLI Crate
This provides the actual deno executable and the user-facing APIs.
The deno crate uses the deno_core to provide the executable.
