Locate the version labeled (or the specific v2 maintenance release).
Open the extracted folder to verify it contains clumsy.exe and the necessary WinDivert.dll modules. Step 3: Launch with Elevated Permissions
— Enable Throttle and Duplicate impairments to see how a voice or video call application handles jitter and out‑of‑order packets. Verify that the application’s jitter buffer and error concealment algorithms perform as expected.

At first glance, the idea of deliberately degrading your network connection seems counterintuitive. Why would anyone want to add latency, drop packets, or throttle bandwidth? The answer lies in software testing and development. clumsy 04 v2 install download
: Some users prefer the official download portal hosted at http://jagt.github.io/clumsy/cn/download . This page automatically provides the correct binary and is often cited in various technical tutorials.
Clumsy allows you to simulate a variety of real-world "broken" network scenarios:
: Navigate to the jagt.github.io download page to find the latest version.
Yes, it is open-source under GPL.
is a niche but useful relic for network fault injection. Always scan downloaded files with Windows Defender or VirusTotal. If you just need basic packet manipulation, grab the latest release from the official GitHub instead.
To give you a better idea of how to use these parameters in practice, here are a few common testing scenarios:
Clumsy allows you to filter specific network traffic (like only "outbound" or specific ports) and apply various impairments: : Delays packets for a set number of milliseconds.
is a powerful, lightweight utility for Windows designed to simulate degraded network conditions in a controlled environment. It is widely used by developers to debug network-related bugs and by gamers to test or exploit latency (often referred to as a "lag switch"). Core Features of Clumsy The tool uses the Locate the version labeled (or the specific v2
Because Clumsy is portable, "installation" is just extracting the files. Locate the downloaded .zip file.
Note: Clumsy does not feature a standard installer. It runs as a portable executable. Step 2: System Requirements & Prerequisites
