Does anyone run Postgres without PgBouncer?
Almost every notable managed Postgres provider bundles a connection pooler, giving us a strong hint that connection management is a product problem rather than a user problem.

Rust SIMD on the GPU
At VectorWare , we are building the first GPU-native software company . Today, we are excited to announce that we can successfully use Rust's portable SIMD ( core::simd ) on the GPU. This milestone marks a significant step towards our vision of enabling developers to write complex, high-performance applications that…

Asynchronous I/O in DuckDB: Work, Thread, Work
Starting with v2.0, scheduled for fall 2026, DuckDB will support asynchronous reads of Parquet and CSV files. This can significantly speed up queries when synchronous I/O does not saturate the available bandwidth, as is typical in EC2/S3 compute-storage setups.

Triton: DirectX 11 Driver for QEMU
In the prequel, we introduced Neptune, a Direct3D protocol forwarding layer for VirtIO. Neptune allowed us to serialize Direct3D API calls across the hypervisor boundary and this allowed us to run Wine games on a Linux guest with a Linux host faster than with DXVK directly in the guest. Admittedly, the payoff there…

Making Postgres 300x faster for analytics: batching, operator fusion, and SIMD
Last week we released version 0.2 of pgrust. This release was all about performance. It’s 10x faster than the previous version of pgrust. On OLTP benchmarks, pgrust is 30% faster than Postgres, and on Clickbench, Clickhouse’s benchmark for analytical databases, pgrust is 300x faster than Postgres. It’s even ahead of…

Smaller, faster, safer: running Kimi and GLM at scale
Serving frontier models like Kimi and GLM means fighting for GPU memory. Here's how we quantize KV caches, compress model weights, and add integrity checks to serve them faster, cheaper, and safely.

Algorithms on billion-scale graph using 10GB RAM: I love DataFusion
In a previous post, I was sceptical about using Apache DataFusion for graph analytics. However, after some thought and experimentation, I changed my mind. I have reconsidered my approach and now have a working implementation of basic graph algorithms, such as WCC, PageRank and MSSP. For example, I can identify weakly…

SQLite in Production: Optimizing WAL Mode, Concurrency, and VFS Layers
Transitioning SQLite from a local development tool to a production-grade database requires a deep understanding of its internal mechanics. This article explores how to tune WAL mode, manage busy handlers, and leverage custom Virtual File System (VFS) layers to achieve ultra-low latency.

How Do I Profile eBPF Code?
If we are running any eBPF workload or writing eBPF code, we want to measure its performance impact, and in this post we will demonstrate an example of how to do it. In this example, our goal is to measure the performance of file open operations, one of the most critical functions in the OS. Our code used file open…
