A website speed test tool to compare uBlock Origin with plain Chrome. Check the weight of your ad implementation. Please consider the environment before loading a bunch of ads on your website.
React is usually pretty fast, but it’s easy to make small mistakes that lead to performance issues. Slow component mounts, deep component trees, and unnecessary render cycles can quickly add up to an…
M-Lab provides the largest collection of open Internet performance data on the planet. As a consortium of research, industry, and public-interest partners, M-Lab is dedicated to providing an ecosystem for the open, verifiable measurement of global network performance. Real science requires verifiable processes, and M-Lab welcomes scientific collaboration and scrutiny. This is why all of the data collected by M-Lab’s global measurement platform are made openly available, and all of the measurement tools hosted by M-Lab are open source. Anyone with time and skill can review and improve the underlying methodologies and assumptions on which M-Lab’s platform, tools, and data rely. Transparency and review are key to good science, and good science is key to good measurement.
Nailgun is a client, protocol, and server for running Java programs from the command line without incurring the JVM startup overhead. Programs run in the server (which is implemented in Java), and are triggered by the client (written in C), which handles all I/O.
UltraESB is the first [and still the only] Open Source Enterprise Service Bus (ESB) to utilize Zero-copy proxying with Memory Mapped files and Java Non-Blocking IO for extreme performance!
Intel® Threading Building Blocks (TBB) offers a rich and complete approach to expressing parallelism in a C++ program. It is a library that helps you take advantage of multi-core processor performance without having to be a threading expert. Threading Building Blocks is not just a threads-replacement library. It represents a higher-level, task-based parallelism that abstracts platform details and threading mechanisms for scalability and performance.
Stressful Application Test (or stressapptest, its unix name) tries to maximize randomized traffic to memory from processor and I/O, with the intent of creating a realistic high load situation in order to test the existing hardware devices in a computer. It has been used at Google for some time and now it is available under the apache 2.0 license.
Cython is a language that makes writing C extensions for the Python language as easy as Python itself. Cython is based on the well-known Pyrex, but supports more cutting edge functionality and optimizations.
This documentation describes the profiler functionality provided in the modules cProfile, profile and pstats. This profiler provides deterministic profiling of Python programs. It also provides a series of report generation tools to allow users to rapidly examine the results of a profile operation.
Usemon is a monitoring system for usage trends, response time and dependency analysis of plain Java applications or big multi-clustered Java Enterprise applications running in production. The proof of Usemon's stability and usefulness is confirmed by the fact that one of the worlds largest telecom operators is running Usemon in a clustered WebSphere environment with over 90 enterprise applications.
Measurement Lab (M-Lab) is an open platform for researchers to deploy Internet measurement tools. By enhancing Internet transparency, we aim to help sustain a healthy, innovative Internet.
Jawr is a tunable packaging solution for Javascript and CSS which allows for rapid development of resources in separate module files. Developers can work with a large set of split javascript files in development mode, then Jawr bundles all together into one or several files in a configurable way.
By using a tag library, Jawr allows you to use the same, unchanged pages for development and production. Jawr also minifies and compresses the files, resulting in reduced page load times.

JumboMem provides a low-effort solution to the problem of running memory-hungry programs on memory-starved computers. The JumboMem software gives programs access to memory spread across multiple computers, providing the illusion that all of the memory resides within a single computer. When a program exceeds the memory in one computer, it automatically spills over into the memory of the next computer.
The developer edition provides ALL of the capabilities of the server edition but limits console and terminal connectivity to the first 45 minutes of a managed JVM's processing. Snapshots taken before the expiration time can still be analyzed offline in the console and the console will reconnect to the JVM once it has been stopped and started.
(FromLinux Magazine Artiecle) Mstone is a multi-protocol stress and performance measurement tool. Mstone can test multiple protocols simultaneously and measures the performance of every transaction. The performance can be graphed throughout the duration of the test.
The Java Application Monitor (JAMon) is a free, simple, high performance, thread safe, Java API that allows developers to easily monitor production applications. * JAMon can be used to determine application performance bottlenecks, user/application intera
InfraRED is a tool for monitoring performance of a J2EE application and diagnosing performance problems. It collects metrics about various aspects of an application's performance and makes it available for quantitative analysis of the application.
