When Go first appeared in November 2009, we didn't hear much about it, and our first interaction happened in 2012 when Go version 1 was officially released by Google. Our team decided to convince our customer to use it for its project, but it was a hard sell, and the customer rejected our recommendation (mostly due to lack of the knowledge in their support team ).

Dynatrace news. Kubernetes has become the industry standard platform for running and managing containerized workloads at scale. The Kubernetes platform, at its core, is designed to maintain and keep up with a defined state for running workloads. In many cases, events are generated as these workloads go through different phases of their life cycles. For instance, events appear when the scheduler performs actions to bring workloads back to a desired state.

Web Performance is important for user experience and business metrics. Estimating its impact is key to be able to prioritize it, yet it’s difficult to quantify its benefits until the work has been done. We need to break this chicken-and-egg loop. This post explains several ways of assessing the potential performance gains with little effort and, more importantly, without actually implementing fixes.

The history of dependency injection (DI) containers in.NET is almost as long as.NET itself. StructureMap and Castle Windsor were released in 2004, Spring.NET in 2005, and more after that, each with their own unique API, some more opinionated than others. And yet each of these libraries fulfills a fairly simple task: a place to hold on to dependencies so that objects can get them when they need them.

Systems performance is an effective discipline for performance analysis and tuning, and can help you find performance wins for your applications and the kernel. However, most of us are not performance or kernel engineers, and have limited time to study this topic. To serve this need I summarized Linux systems performance in 40 minutes at USENIX LISA 2019, touring six important areas: observability tools, methodologies, benchmarking, profiling, tracing, and tuning.

First things First. CDC 9762 SMD disk drive from 1974. Why do we tend to use 1MB IO sizes for throughput benchmarking? To achieve the maximum throughput on a storage device, we will usually use a large IO size to maximize the amount of data is transferred per IO request. The idea is to make the ratio of data-transfers to IO requests as large as possible to reduce the CPU overhead of the actual IO request so we can get as close to the device bandwidth as possible.
