In some cases, yes, but it depends on your goal, and you need to be smart about it. If your goal is increased performance, remember that the Windows CPU Scheduler tries to manage which threads are on what cores itself, and it’s not entirely dumb. So, when you micro-manage CPU affinities, you are second guessing […]

Recently I have seen a new round of malware-laden cracks and keygens for Process Lasso Pro. You MUST understand that your security software is not absolute protection. It’s not even close. I believe the real-world, 0-day malware detection rate lingers somewhere around 40%. If security software protected you 100%, we’d not have a malware problem in the […]

Many users disable Hyper-Threading in an effort to achieve performance consistency. When the technology first emerged, this was good advice for users with real-time application. However, now that CPU architectures have matured, as have operating system CPU schedulers, the question of whether to disable Hyper-Threading is a little more complicated. Modern desktop and laptop CPUs […]

In NT6 (Vista), a major kernel and subsystems redesign occurred. The refactored subsystems are still used in Windows 10 for desktop applications, thus are still important, especially after the arguable ‘failure’ of Windows 8 Store Apps. The subsystem in question here is the Task Scheduler. In Windows XP and before, when an application wanted to start itself at […]

The Windows Registry is meant to serve as a shared storage location for system and application settings. It is essentially a database, has per-user hives, multiple data types, and is generally well-suited for it’s purpose. Lookups (retrieval) of registry values are extremely rapid since the keys are traversed using an optimal data tree (an algorithm […]

When CPU affinity matters Case 1: Limit a Process’s CPU Consumption One common case where CPU affinity matters is one of CPU resource allocation. Specifically, keeping a process limited to using a certain amount of CPU time or percent of the total available. By limiting a process to specific cores, you have the ability to […]
