A lot of companies—even if they are aware that performance is key to their business—are often unsure of how, when, or where performance testing sits within their development lifecycle. To make things worse, they’re also usually unsure whose responsibility performance measuring and monitoring is. The short answers are, of course ‘all the time’ and ‘everyone’, but this mutual disownership is a common reason why performance often gets overlooked.

The private bpftrace repository has just been made public, which is big news for DTrace fans. Created by Alastair Robertson , bpftrace is an open source high-level tracing front-end that lets you analyze systems in custom ways. It's shaping up to be a DTrace version 2.0: more capable, and built from the ground up for the modern era of the eBPF virtual machine. eBPF (extended Berkeley Packet Filter) is in the Linux kernel and is the new hotness in systems engineering.

A look at the roles of architect and strategist, and how they help develop successful technology strategies for business. There are two jobs in the world that people want to do the most while knowing the least about: architect and strategist. I should start by saying this section does not offer a treatise on how to do architecture. I'm offering an overview of my perspective on the field, which I hope is a unique and interesting take on it, in order to provide context for the work at hand: devisi

When undertaking any sort of performance optimisation work, one of the very first things we learn is that before you can improve performance you must first measure it. Without being able to measure the speed at which something is working, we can’t tell if the changes being made are improving the performance, having no effect, or even making thin

In the context of providing managed WordPress hosting services, at Presslabs we operate with lots of small to medium-sized databases, in a DB-per-service model, as we call it. The workloads are mostly reads, so we need to efficiently scale that. The MySQL® asynchronous replication model fits the bill very well, allowing us to scale horizontally from one server—with the obvious availability pitfalls—to tens of nodes.

Typically, when we modify a program, we’d like to run it to verify our changes. Before booting a compiled Linux kernel image on actual hardware, it can save us time and potential headache to do a quick boot in a virtual machine like QEMU. as a sanity check. If your kernel boots in QEMU, it’s not a guarantee it will boot on metal, but it is a quick assurance that the kernel image is not completely busted.

I’m a big fan of automated testing. The math just works out. Why spend hours running a series of test cases when a computer can do it in seconds. With benefits like this, my zeal for automated testing can make it seem like I think that all testing should be automated. However, this couldn’t be farther from the truth. There is little room in software development for pure rote manual testing, but that’s not the only reason to manually test software.

Some time ago, a customer had a performance issue with an internal process. He was comparing, finding, and reporting the rows that were different between two tables. This is simple if you use a LEFT JOIN and an IS NULL comparison over the second table in the WHERE clause, but what if the column could be null? That is why he used UNION, GROUP BY and a HAVING clauses, which resulted in poor performance.
