Rust Query Engine Sees Slower Performance After Replacing MMAP with Io_uring

By PulseAugur Editorial · [3 sources] ·

A technical blog post from Conviva details an experiment where they replaced the MMAP memory management technique with io_uring in their Rust query engine. Contrary to expectations, this change resulted in a performance decrease, indicating that io_uring was not a suitable replacement for MMAP in this specific context. The findings highlight the nuanced performance characteristics of different system-level programming interfaces. AI

IMPACT This research explores system-level optimizations that could indirectly impact AI model training or inference performance by improving underlying infrastructure efficiency.
