I'll copy from Twitter[1]:

@zackbloom @jgrahamc I can't find it in the docs on AWS site, but I've read that AWS Lambda scales CPU linearly until 1.5GB, then gives you 2nd thread/core and again scales linearly until 3GB. If your PBKDF2 was single threaded, Lambda bigger than 1.5GB is wasted.

Replying to @ZTarantov @Cloudflare @jgrahamc I can't think of a way to test that within the Node code. The only option seems to be to update the C++ version (or some other language) to use multiple threads.

Yes, Lambda functions use a second core above 1536MB of memory. Back in the past they had it in their documentation, but removed it at a certain point. Also see: https://stackoverflow.com/questions/34135359/whats-the-maxim...

It might not be true any longer if they removed it from the documentation.
