My post Good Times for Load Testing was published in 2014. It is difficult to believe that 5 years passed… Are times still good for load testing? Well, yes and no. I am not so upbeat as I was in 2014. If we speak about commercial load testing tools, we see rather a shrinking market and not too much innovation recently. If we speak about open source tools, we definitely see some improvement – but in many areas they are still behind the best commercial tools (yes, many may not need these adv

It’s true that what might be considered the “most important” or “best” web performance metrics can vary by industry. For example, a media organization may be interested in tracking Time to Interactive because its site relies on third-party advertising for revenue, while an ecommerce business might want to dig deeper into First Meaningful Paint so it can ensure that customers can quickly take action to purchase an item.

The need for good manners in shared spaces turns out to be important not just for people, but for your Docker containers too. When you’re running in the cloud your containers are in a shared space; in particular they share the CPU’s memory hierarchy of the host instance.

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.

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.

The other is doing reads and writes from the main datafiles. Since the DB is small (50% the size of the Linux RAM) – the database is mostly cached on the read side – so we only see writes going to the DB files.
