I'm thinking to remove the cache feature.
There're two main reasons:

Adding a private symbol field into the user's data is not a good idea. Because we don't know what kind of data will pass in

For example:

const perf_hooks = require('perf_hooks')

function f () {
  console.log('hello, world!')
}
Object.freeze(f)
perf_hooks.performance.timerify(f)

/Users/himself65/Code/node/out/Debug/node /Users/himself65/Code/test/index.js
node:internal/perf/timerify:123
    ObjectDefineProperties(fn, {
    ^

TypeError: Cannot define property Symbol(kTimerified), object is not extensible
    at defineProperties (<anonymous>)
    at Performance.timerify (node:internal/perf/timerify:123:5)

caching by default will increase unnecessary complexity.

The original PR(#37136) only has 1 parameter which is fn. At this time, cache a function is very simple. However, the next PR adds one more parameter histogram(#37475), and this causes unexpected code behavior inconsistent today.
So if we finished a perfect cache system for now and merge it. But what if we add one more parameter in the future?

Moreover, I think users could cache a timerify function if they want. So I will remove cache stuff in this PR

What's more, I found that the commit queue always failed because the commit message tool didn't consider the Co-author-by field to the tailer.
So the final check failed
