ScalaMeter is a microbenchmarking and performance regression testing framework for the JVM platform that allows expressing performance tests in a way which is both simple and concise.  It can be used both from Scala and Java. write performance tests in a DSL similar to ScalaTest and ScalaCheck specify test input data specify how test results are collected organize performance tests hierarchically

"Some of the topmost brands have recently ditched native and gone the hybrid way. With the new hybrid frameworks like Ionic, Phonegap etc becoming more mature, one cannot assume that hybrid apps perform worse anymore. In fact, a recent Gartner report says that by next year more developers will be going the hybrid way and by another account, the average end user ratings of hybrid apps are already 12 percent better than native apps."

"Since earlier this year, the Performance Engineering Group at Red Hat has run huge amounts of microbenchmarks, benchmarks and application workloads in Docker containers."

Spire is a numeric library for Scala which is intended to be generic, fast, and precise. Using features such as specialization, macros, type classes, and implicits, Spire works hard to defy conventional wisdom around performance and precision trade-offs. A major goal is to allow developers to write efficient numeric code without having to "bake in" particular numeric representations. In most cases, generic implementations using Spire's specialized type classes perform identically to corresponding direct implementations.

"Colossus is a lightweight framework for building high-performance applications in Scala that require non-blocking network I/O. In particular Colossus is focused on low-latency stateless microservices where often the service is little more than an abstraction over a database and/or cache. For this use case, Colossus aims to maximize performance while keeping the interface clean and concise."

"Envoy is a high performance C++ distributed proxy designed for single services and applications, as well as a communication bus and "universal data plane" designed for large microservice "service mesh" architectures. Built on the learnings of solutions such as NGINX, HAProxy, hardware load balancers, and cloud load balancers, Envoy runs alongside every application and abstracts the network by providing common features in a platform-agnostic manner. When all service traffic in an infrastructure flows via an Envoy mesh, it becomes easy to visualize problem areas via consistent observability, tune overall performance, and add substrate features in a single place."

"Caffeine is a high performance, near optimal caching library based on Java 8."

This document provides information on typical command-line options and environment variables that can affect the performance characteristics of the Java HotSpot Virtual Machine.

What is Graphite? Graphite is a highly scalable real-time graphing system. As a user, you write an application that collects numeric time-series data that you are interested in graphing, and send it to Graphite's processing backend, carbon, which stores the data in Graphite's specialized database. The data can then be visualized through graphite's web interfaces. Who should use Graphite? Graphite is actually a bit of a niche application. Specifically, it is designed to handle numeric time-series data. For example, Graphite would be good at graphing stock prices because they are numbers that change over time. However Graphite is a complex system, and if you only have a few hundred distinct things you want to graph (stocks prices in the S&P 500) then Graphite is probably overkill. But if you need to graph a lot of different things (like dozens of performance metrics from thousands of servers) and you don't necessarily know the names of those things in advance (who wants to maintain such huge configuration?) then Graphite is for you.

"In 2010 we led the seed round for Docker (formerly known as dotCloud) for one simple reason: devops means that the way applications are packaged, deployed, and run is fundamentally changing (though Docker's business model has evolved since its early days as a PaaS vendor, the fundamental premise is the same).  Rather than requiring custom configurations and painstaking management, Docker "containerizes" applications components such that every container is lightweight and behaves consistently.  Applications and their underlying components can be programmatically deployed, managed and moved on ever-changing cloud infrastructure without a hint of operating system or hardware configuration.  In a pre-Docker world, companies with tremendous and evolving application demands looked to virtualization as a way of abstracting their infrastructure, but paid a tax in dollars and performance for doing so. In the future we think of Docker will take the mantle as the VMware of the devops world, with containers as the ultimate devops platform."

ScalaNLP is a suite of machine learning and numerical computing libraries. ScalaNLP is the umbrella project for Breeze and Epic. Breeze is a set of libraries for machine learning and numerical computing. Epic (coming soon) is a high-performance statistical parser.

"Leaflet is a modern open-source JavaScript library for mobile-friendly interactive maps. It is developed by Vladimir Agafonkin with a team of dedicated contributors. Weighing just about 31 KB of JS, it has all the features most developers ever need for online maps. Leaflet is designed with simplicity, performance and usability in mind. It works efficiently across all major desktop and mobile platforms out of the box, taking advantage of HTML5 and CSS3 on modern browsers while still being accessible on older ones. It can be extended with many plugins, has a beautiful, easy to use and well-documented API and a simple, readable source code that is a joy to contribute to."
