It's an insight from Heidi Howard et al. that came out after VSR: https://arxiv.org/abs/1608.06696 and can be applied to VSR (and others). The basic idea is pretty simple. In VSR, there are two main phases: 1. Le

Tobi here from TB. Great question, and it's important to be nuanced here. It really depends on the problem space. For example, many OLAP workloads (analytical) contain large amounts of parallelizable work, then multi-core execution is

Hi, Tobi here from TB. Great question! Generally, 130 ms of network latency is challenging, and there often isn't an easy way around it as you're ultimately constrained by the speed of light (e.g. cross region deployments). That s

Pretty nice library! Personally, I think having a language-native library is great. The only downside is that it becomes a long-term commitment if it needs to stay in sync with the development of io_uring. I wonder whether it would be a goo

There is some interesting ongoing research on eBPF and uring that you might find interesting, e.g., RingGuard: Guarding io_uring with eBPF ( https://dl.acm.org/doi/10.1145/3609021.3609304 ).

Great point. It is indeed the case that most io_uring libraries are lagging behind liburing. There are two main reasons for this: (1) io_uring development is moving very quickly (see the linked figure in another comment), and (2) liburing i

The post is updated now to reflect this.

Good catch! We will fix this in the next version and change it to brk/sbrk or mmap

We also wrote up a very concise, high-level summary here, if you want the short version: https://toziegler.github.io/2025-12-08-io-uring/
