Sidekiq concurrency limit per worker

Crunch is an alternative MongoDB driver with an emphasis on high concurrency, atomic update operations, and document integrity. It uses the Rev event library for non-blocking writes and reads. Its API is more limited than the official Mongo Ruby driver, but simpler and more Rubyish.

Armstrong is an Mongrel2 fronted, actor-based web development framework similar in style to sinatra. With natively-threaded interpreters (Rubinius2), Armstrong provides true concurrency and high stability, by design.

Scrapetor is a Ruby HTML parsing + scraping toolkit. The parser is a native C arena DOM with structural indexes built at parse time and NEON SIMD scanners in the SAX hot loop. A streaming extraction engine compiles the schema DSL into a single forward pass — no DOM materialised, one Ruby boundary...

A high-performance NATS client built on the async framework, providing fiber-based concurrency for better resource efficiency. Built on top of nats-pure with full API compatibility. WARNING: This project was developed entirely by the Windsurf AI code agent and should be considered experimental.

Angstrom is an Mongrel2 fronted, actor-based web development framework similar in style to sinatra. With natively-threaded interpreters (Rubinius2), Angstrom provides true concurrency and high stability, by design.

A collection of utility helpers for Ruby including graphing, configuration management, concurrency, system operations, multimedia handling, and more.

RobotLab is a Ruby framework for building and orchestrating multi-robot LLM workflows. Built on ruby_llm, it provides robots with template-based prompts, tools, and shared memory; networks for coordinating multiple robots with intelligent routing; MCP (Model Context Protocol) integration for exte...

Clones a SourceForge project's directory tree and downloads its files by scraping the Files pages (SourceForge has no official API). Runs in two stages - map the tree, then download - with a live status bar and optional JSON metadata. Supports concurrency, file integrity verification (MD5 / SHA1)...

Mutable and immutable concurrency variable

HttpLoader is a powerful, high-concurrency performance and load testing console tool. Built on asynchronous Ruby, it evaluates server limits by opening massive numbers of persistent connections and holding them open. It utilizes event-driven I/O with optional periodic ping requests to keep connec...

Omnibus concurrency library for Ruby

Concurrency based polling.

Collection of utilities for managing concurrency

Massive concurrency with message-passing and stuff.

A Ruby HTTP server combining Falcon-class fiber concurrency with Puma-class compatibility.

A Ruby web server designed to have a predictable and simple concurrency model, and to be capable of running in a pure-ruby environment.

An implementation of the CSP concurrency primitives

Retlang is a high performance C# threading library. The library is intended for use in message based concurrency similar to event based actors in Scala. The library does not provide remote messaging capabilities. It is designed specifically for high performance in-memory messaging.

Stages perform_later into a dedicated table, runs a tick loop that admits jobs through declared gates (throttle, concurrency), then forwards survivors to the real ActiveJob adapter. Embedded as a periodic job. Compatible with good_job and solid_queue.
