Performance Testing in Java

Writing software is regarded by many developers as a craft or an art. However when it comes to performance tuning and/or testing many believe it to be more of a dark art. Nothing farther from the truth. We can gain a lot by applying a concrete methodology and similar reasoning techniques we follow when writing production code. There are tools in the Java space that can help us get better measurements and results, JMeter perhaps one of the most well known, JMH is probably the next likely candidate. We'll discuss these tools and some techniques that should make engaging in performance testing a rewarding experience.

High Performance Managed Languages

Common wisdom dictates that native languages are the only means of building high-performance applications. How do managed runtimes such as those available to .NET, Java, and even JavaScript, yes even JavaScript compare? Many applications requiring high-performance are now developed for managed...

Async Or Bust!?

Asynchronous is the new normal! Or is it? Many of our languages, runtimes, and libraries are built around synchronous behaviour and usage as we keep trying to make RPC work by force of will. Primitives such as futures and promises present a synchronous facade. Blocking I/O dominates the vast...

In-Memory Caching: Curb Tail Latency with Pelikan

In-memory caching in a distributed setting is widely used these days, and users usually expect it to be "fast and cheap". One important but often overlooked aspect of cache is tail latency– for many real-time applications, tail latency plays an outsized role in determining the overall...
