Just to clarify: the spinning on CMPXCHG is not also a bad idea, the YieldProcessor is correct (a pause), but inside the CMPXCHG loop it should be spinning on a pure unlocked load. Is that correct?

I do agree it is somewhat fishy of the large performance difference not being explained by comparatively fundamentally poor data access patterns. However, Redis runs as an out of process server with marshaling and unmarshaling of data acros

Processes and threads on NT are distinct nominative types of objects (in a system where “object” has a much more precise meaning) and the GP is at least correct that the former are not schedulable entities. This distinction doesn’t really e

Most of the networking stuff from the 80s at least wasn’t particularly well made, it’s just been maintained and significantly reworked to not have massive security vulnerabilities.

In contrast when I see software from the 80s that is not a security and performance disaster it’s because of continued investment and most of the basics like string handling have been replaced with bespoke or third party libraries and IO he

This isn't right. O_NONBLOCK doesn't mean the pipe doesn't stall, it just means you get an immediate errno and don't block on the syscall in the kernel waiting and this is specific to the file description, for which a pi
