Load testing with Fiddler

For one of our projects, we wanted to do some load testing to validate if our infrastructure was sufficient. We decided not to use the Visual Studio Load testing features.

Instead we choose StressStimulus, a free Fiddler plug-in for easy load testing of web applications.

StresStimulus plays back HTTP requests recorded in Fiddler to create high concurrency workload on web applications. You can configure virtual users, think time, and number of test iterations or test duration.

After test completion, StresStimulus determines average performance of the test scenario. It breaks down response times of every page between server and network times to identify areas with scalability problems.

StresStimulus can be downloaded at http://stresstimulus.stimulustechnology.com. It is free, allows unlimited virtual users, and no registration is required.

Remark: When we tried to install the plugin on a 64bit machine, the installation failed. This is a known bug and the problem will be fixed in the next release. You can already download the alpha here.

Azure DevOps/ GitHub emoji

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t

DevToys–A swiss army knife for developers

As a developer there are a lot of small tasks you need to do as part of your coding, debugging and testing activities. DevToys is an offline windows app that tries to help you with these tasks. Instead of using different websites you get a fully offline experience offering help for a large list of tasks. Many tools are available. Here is the current list: Converters JSON <> YAML Timestamp Number Base Cron Parser Encoders / Decoders HTML URL Base64 Text & Image GZip JWT Decoder Formatters JSON SQL XML Generators Hash (MD5, SHA1, SHA256, SHA512) UUID 1 and 4 Lorem Ipsum Checksum Text Escape / Unescape Inspector & Case Converter Regex Tester Text Comparer XML Validator Markdown Preview Graphic Color B
