pnpm add slow-down in v8 vs v7

[vjpr]

pnpm add for a single package used to take <10s in v7. Now it's over a minute which makes it hard to work.

I used the --reporter=ndjson to time how long each stage takes:

scope
scope 2.3s
pnpm
pnpm 194ms
package-manifest
package-manifest 447ms
context
context 25ms
stage resolution_started
stage resolution_started 22.9s
install-check
install-check 22.9s
package-manifest
package-manifest 2.4s
stage resolution_done
stage resolution_done 176ms
stats
stats 1ms
stage importing_started
stage importing_started 186ms
stats

link
link 1ms
stage importing_done
stage importing_done 28ms
pnpm

bins-conflict

global 276ms
bins-conflict
bins-conflict 1ms
global
global 76ms
summary
summary 22ms
peer-dependency-issues
peer-dependency-issues 1ms
execution-time

Looks like these stages are the main culprits...although my way of timing may not be totally accurate. I'm just measuring the time between each message and a different type of message.

stage resolution_started
stage resolution_started 22.9s
install-check
install-check 22.9s

I already tried setting: verify-store-integrity=false

Any guidance?

Is there a better way to time each stage?

I couldn't find any usage of node:diagnostics_channel or performance.now...
