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.

.NET 8–Keyed/Named Services

A feature that a lot of IoC container libraries support but that was missing in the default DI container provided by Microsoft is the support for Keyed or Named Services. This feature allows you to register the same type multiple times using different names, allowing you to resolve a specific instance based on the circumstances. Although there is some controversy if supporting this feature is a good idea or not, it certainly can be handy. To support this feature a new interface IKeyedServiceProvider got introduced in .NET 8 providing 2 new methods on our ServiceProvider instance: object? GetKeyedService(Type serviceType, object? serviceKey); object GetRequiredKeyedService(Type serviceType, object? serviceKey); To use it, we need to register our service using one of the new extension methods: Resolving the service can be done either through the FromKeyedServices attribute: or by injecting the IKeyedServiceProvider interface and calling the GetRequiredKeyedServic...

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...
