Thread-per-core

I want to address a controversy that has gripped the Rust community for the past year or so: the choice by the prominent async “runtimes” to default to multi-threaded executors that perform work-stealing to balance work dynamically among their many tasks. Some Rust users are unhappy with this decision, so unhappy that they use language I would characterize as melodramatic.

[…]

What these people advocate instead is an alternative architecture that they call “thread-per-core.” They promise that this architecture will be simultaneously more performant and easier to implement. In my view, the truth is that it may be one or the other, but not both.

A very academic discussion.
