outdated command is inefficient

[aparajita]

pnpm version:

5.1.8

Code to reproduce the issue:

pnpm outdated

Behavior:

I hope for pnpm outdated to be as fast as updates. Here's the results for pnpm outdated vs updates in a project with 94 top level dependencies:

$ time pnpm outdated
pnpm outdated  2.44s user 0.60s system 30% cpu 9.856 total

$ time updates
updates  1.19s user 0.15s system 74% cpu 1.810 total

updates is >2x faster. And it uses 6x less bandwidth!

Since updates is open source, why not just use their algorithm (with attribution of course)?

Additional information:

• node -v prints: v14.3.0
• Windows, OS X, or Linux?: macOS

We have the fastest installation, so our codebase should be able to have the fastest outdated command. There are probably just some inefficiencies that needs to be fixed.

You might as well look at update's code for clues. 😁

Try 5.2.0

Will do. I'll do a new comparison with updates on the same repo.

pnpm outdated  1.29s user 0.29s system 80% cpu 1.958 total
updates  1.12s user 0.14s system 100% cpu 1.257 total

Much better! But still 56% slower than updates.

Maybe we can come up with some other improvements but I don't have more ideas at the moment. There is nothing special in the codebase of "updates". They use npm's package for fetching metadata. But they don't read any of the npm configs (we do). And they probably have less code, so the CLI startup is faster.

Our CLI startup is pretty slow. Probably that's the reason.

It isn't worth worrying about. 56% slower is way better than 200% slower.
