We’ve written tons of articles giving you step-by-step advice on how to make your website faster – but not everyone wants to go through lots of steps. Many people reach out to us asking what is the #1 most important bang-for-your-buck tip on optimizing your website’s speed. Good news is that we can answer that with a simple response.

Raise your hand if you've ever poured countless hours into making a fast website, only to have it slowly degrade over time. New features, tweaks, and Super Important Tracking Snippets all pile up and slow things down. At some point you'll be given permission to "focus on performance" and after many more hours, the website will be fast again. But a few months later, things start to slow again.

Growing up in performance engineering in the last decade, it was almost impossible to think of simulating load using a real browser because a performance engineer would need a lot of machines to simulate load using a real browser. Performance engineers used to have a couple of desktop or servers to simulate hundreds and thousands of users load. Their preferred choice used to be to capture HTTP/s requests using tools like LoadRunner , JMeter , Soasta , and Neoload.

Dynatrace news. In my colleague Andi Grabner’s recent blog on Automated Deployment and Architectural Validation, he notes that, based on a recent ACM survey , validating deployment still seems to be a semi-automated task for most software delivery teams. And, with the length of manual work directly contributes to the overall Commit Cycle Time, this to me shows room for automation and improvements!

When building a web application there is a good chance you’re going to need to work with images eventually, even if it is something as simple as allowing a user to upload a profile image. In theory this is a simple task, but in reality, your website theme is probably anticipating images of a certain resolution or aspect ratio. If the user tries to upload an image that doesn’t meet your requirements, it might break your theme.

Towards multiverse databases Marzoev et al., HotOS’19. A typical backing store for a web application contains data for many users. The application makes queries on behalf of an authenticated user, but it is up to the application itself to make sure that the user only sees data they are entitled to see. Any frontend can access the whole store, regardless of the application user consuming the results.

Introduction. In testing, it is always important to test application features with different sets of data. Testing with one set of data that we use during recording or while creating a base script will not confirm the functionality of the application alone. For example: When we are doing a login test, it is extremely important to test with all possible valid and invalid credentials to ensure login functionality is working as expected.
