bpftune aims to provide lightweight, always-on auto-tuning of system behaviour. The key benefit it provides are
-
by using BPF observability features, we can continuously monitor and adjust system behaviour.
-
because we can observe system behaviour at a fine grain (rather than using coarse system-wide stats), we can tune at a finer grain too (individual socket policies, individual device policies etc).

Postgres performance at any scale. PostgreSQL Tuning
Deliver consistent database performance and availability through intelligent tuning advisors and continuous database profiling.
A performance dashboard for Postgres
Wireit upgrades your npm/pnpm/yarn scripts to make them smarter and more efficient.
Statistically Sound Performance Evaluation.
Stabilizer is a system that enables the use of the powerful statistical techniques required for sound performance evaluation on modern architectures. Stabilizer forces executions to sample the space of memory configurations by repeatedly rerandomizing layouts of code, stack, and heap objects at runtime.
BOLT is a post-link optimizer developed to speed up large applications. It achieves the improvements by optimizing application's code layout based on execution profile gathered by sampling profiler, such as Linux perf tool.
Towards Minimum MSE Photo-Realistic Image Restoration.
PMRF is a novel photo-realistic image restoration algorithm. It (provably) approximates the optimal estimator that minimizes the Mean Squared Error (MSE) under a perfect perceptual quality constraint.
Statistically rigorous benchmark runner for the web.
tachometer is a tool for running benchmarks in web browsers. It uses repeated sampling and statistics to reliably identify even tiny differences in runtime.
A simple profiler for PHP.
A simple & straight-to-the-point PHP profiling extension with its built-in web UI.
Repack docker images to optimize for pulling speed.
This tool repacks a Docker image into a smaller, more efficient version that makes it significantly faster to pull. It does this by using a few different techniques such as removing redundant data and improving compression ratios.
This book uses MySQL challenges as case studies to explore problem analysis and resolution strategies. Readers will gain a deeper appreciation for logical reasoning, data structures, algorithms, and more through practical examples and insightful discussions.
PGTune calculate configuration for PostgreSQL based on the maximum performance for a given hardware configuration.
It isn't a silver bullet for the optimization settings of PostgreSQL. Many settings depend not only on the hardware configuration, but also on the size of the database, the number of clients and the complexity of queries. An optimal configuration of the database can only be made given all these parameters are taken into account.
Optimizes static websites for best user experience and best Core Web Vitals scores.
jampack is a post-processing tool that takes the output of your Static Site Generator (aka SSG) and optimizes it for best user experience and best Core Web Vitals scores.
Compress WebP, PNG, JPEG and Gif images intelligently.
Pic Smaller is a super easy-to-use online image compression tool. Its UI is intuitive and supports compression configuration. At the same time, because it is purely local compression without any server-side logic, it is completely safe.
Port of OpenAI's Whisper model in C/C++
deep learning at the speed of light.
Luminal is a deep learning library that uses composable compilers to achieve high performance.

libreactor is a high performance, robust and secure, generic event-driven application framework for Linux.
libreactor is a high performance, robust and secure, generic event-driven application framework for Linux. The design goal is to minimize software overhead, cpu usage, energy consumption and environmental footprint. libreactor is directly built on top of the Linux kernel io_uring system call interface, offering both much simplified access to low level asynchronous kernel calls, as well as high level event-driven abstractions such as HTTP servers. Furthermore libreactor is built completely without third-party dependencies, minimizing supply chain risk.
PHP Benchmarking framework.
PHPBench is a benchmark runner for PHP analogous to PHPUnit but for performance rather than correctness.
