kristoff wrote the same about performance > More generally, RAII is a feature that exists in tension with the approach of operating on items in batches, which is an essential technique when writing performance-oriented software. > And it doesn’t end here: operating in batches by using memory arenas, for example, is also a way to reduce memory ownership complexity, since you are turning orchestration of N lifetimes into 1. > In this video Casey Muratori describes how going from thinking about individual allocations to thinking in batches is a natural form of progression for a programmer. > Extremely popular talk on the advantages of looking at problems as data transformation pipelines, where Mike Acton shows how common approaches in C++ (RAII being one of them) are antithetical to the goal of creating performant code. https://kristoff.it/blog/raii-rust-linux/ |
