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.

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

Over the last decade, flagship processors from Intel and AMD have been eking out only marginal cross-generational single threaded (ST) performance gains. Instead, the focus has been on boosting aggregate performance by increasing core count. While throughput performance is important, especially in data-centers, single threaded performance remains a pivotal metric for a large swath of application domains (HPC, Finance etc.).

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.
