Should I Micromanage CPU Affinities?

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 […]

Do Not Risk Your PC with Cracks and Keygens!

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 […]

Spreading the Load – CPU Affinities and Hyper-Threading

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 […]

Bitsum Acquires EV Code Signing Certificate

Our existing code signing certificate was due to expire this year, so it was time to renew. This time around we found the certificate authorities were advertising Extended Validation (EV) code signing certificates, which are a-kin to EV/OV SSL (TLS) certificates that result in the larger green bar on some web sites. Extended Validation means the […]

Bitsum’s CPU Affinity Textual Representation

During the course of development of Process Lasso and other Bitsum software, it became apparent that we needed a way to express CPU affinities in an efficient, shorthand, textual manner. This specification became used by the Default CPU Affinities and, in fact, all CPU Affinity settings of Process Lasso. The specification is quite simple. It is […]

ParkControl v1.0.1.1 Released

This minor update to ParkControl offers several language refreshes and corrects an error in the last version where the licensing information wasn’t as visible as it should have been. It also adds dual-signing with SHA1 and SHA2, as will be the case of all Bitsum binaries going forward. Other than that, not anything worth writing home about. […]

About Task Scheduler 2.0, and Why You Should Never Disable It

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 […]
