Concurrency is not parallelism, friend.

leshow • Dec 8, 2016 • View on HN

i think you are confusing concurrency with parallelism.

davidw • Mar 10, 2018 • View on HN

Parallelism isn't concurrency, though!

You are confusing parallelism with concurrency. It definitely can be a problem.

Narishma • Jun 4, 2016 • View on HN

This is about concurrency, not parallelism.

eptcyka • Mar 13, 2021 • View on HN

You are mistaking parallelism for concurrency.

duped • Oct 13, 2023 • View on HN

You're mixing up concurrency with parallelism.

chrisseaton • Jan 5, 2020 • View on HN

That's great for concurrency... but what about parallelism?

arethuza • Feb 20, 2019 • View on HN

Aren't concurrency and parallelism orthogonal?

Concurrency is not Parallelism. You should watch this quintessential talk about the difference - https://www.youtube.com/watch?v=oV9rvDllKEg
