crypto.pbkdf2Sync - ~40% performance drop from node 14/16 to 18/20

[NewEraCracker]

Version

v18.16.0

Platform

Microsoft Windows NT 10.0.19045.0 x64

Subsystem

crypto

What steps will reproduce the bug?

const crypto = require('crypto');
const ts = Date.now();
crypto.pbkdf2Sync('XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX', 'XXXXXXXXXXXXXXXXXXXXXXXXXXX', 100000, 32, 'sha512');
console.log(Date.now() - ts);

How often does it reproduce? Is there a required condition?

The code snippet in varying platforms logs lower numbers when ran on Node.js 14 & 16 (better) comparatively to Node.js 18 & 20 (worse).

Examples:

Windows 10

node 14/16: 70
node 18/20: 99

Ubuntu 20

node 14/16: 177
node 18/20: 240

And I've encountered similar results on Ubuntu 22, Debian 11, etc...

What is the expected behavior? Why is that the expected behavior?

I would expect no performance regression.

What do you see instead?

Performance regression ranging from ~30% to ~40%

Built Node.js 18 from source with OpenSSL 1.1.1t on the Ubuntu 20 system - the build took some hours.

$ node poc.js
162
$ node poc.js
160

At least there is a workaround now. Thanks for the info!
