Command line interface for testing internet bandwidth using speedtest.net. It is not a goal of this application to be a reliable latency reporting tool. Latency reported by this tool should not be relied on as a value indicative of ICMP style latency. It is a relative value used for determining the lowest latency server for performing the actual speed test against. Speedtest CLI brings the trusted technology and global server network behind Speedtest to the command line.

Ethr is a cross-platform network performance measurement tool written in golang. The goal of this project is to provide a native tool for comprehensive network performance measurements of bandwidth, connections/s, packets/s, latency, loss & jitter, across multiple protocols such as TCP, UDP, HTTP, HTTPS, and across multiple platforms such as Windows, Linux and other Unix systems. Ethr takes inspiration from existing open-source network performance tools and builds upon those ideas. For Bandwidth measurement, it is similar to iPerf3, for TCP & UDP traffic. iPerf3 has many more options for doing such as throttled testing, richer feature set, while Ethr has support for multiple threads, which allows it to scale to 1024 or even higher number of connections, multiple clients communication to a single server etc. ...

...It operates at the HTTP application layer, giving developers more control over requests and responses than basic TCP throttling tools. Its core model uses poisons to alter traffic and rules to decide when those alterations should apply. Tests can inject latency, limit bandwidth, return errors, manipulate payloads, or combine several adverse conditions. Rules can filter traffic by route, headers, query values, methods, bodies, and other request properties. A hierarchical middleware architecture makes the proxy extensible with custom behaviors and reusable modules. The repository was archived in 2023, so it is primarily useful as a reference or for legacy testing setups.

...To support more realistic testing of Internet server applications, we develop a live flow reproduction tool - TCPCopy, which could generate the test workload that is similar to the production workload. Currently, TCPCopy has been widely used by companies in China. TCPCopy has little influence on the production system except occupying additional CPU, memory and bandwidth. Moreover, the reproduced workload is similar to the production workload in request diversity, network latency and resource occupation. TCPCopy consists of two parts, TCPCopy and intercept. While TCPCopyruns on the online server and captures the online requests, intercept runs on the assistant server and does some assistant work, such as passing response info to TCPCopy.

Lepton image compression, saving 22% losslessly from images at 15MB/s. Lepton achieves a 22% savings reduction for existing JPEG images, by predicting coefficients in JPEG blocks and feeding those predictions as context into an arithmetic coder. Lepton preserves the original file bit-for-bit perfectly. It compresses JPEG files at a rate of 5 megabytes per second and decodes them back to the original bits at 15 megabytes per second, securely, deterministically, and in under 24 megabytes of...

...For testing an application which has a form or request that takes multiple data entries from a large no of users and the data entries are required to be unique for different users, it becomes a redundant work to type .csv files with unique data entries. Bandwidth Throttling: More enhancements such as follows are also implemented. -Bandwidth throttling -Dynamic bandwidth throttling -IP Spoofing -TPC-C Sampler -Smtp config element -Filterd Results Plugin please refer description.pdf in files.

...So this is in essence a Denial of Service application, because of that you have to remember not to use this for malicious purposes, the program calls back home on first run, so don't do any funny business ;-D Another thing to bear in mind when using this, is that you will have to have more bandwidth than the "victim", unless it is a really weak host you are flooding.
