Windows Performance Exploitation | LagtencySkip to main content

A few months ago, I decided to revive an almost decade-old laptop that had been sitting unused for years. So I performed a clean Windows installation, and set it up as a secondary machine for light tasks. It went largely as expected: the default Windows was fully lagged. What surprised me was how poorly a completely default Windows 11 installation would run on hardware that officially meets Microsoft’s requirements, except the CPU. Although the CPU might seem like the obvious culprit for such severe lag, I didn’t believe that narrative, and my subsequent test results didn’t corroborate it either.The hardware was certainly a limitation, but the operating system turned out to be a much larger contributor than expected. And this is not a new problem; discussions surrounding Windows resource consumption, background activity, and increases in hardware requirements have existed for years.For example, NVIDIA engineers presented measurements showing that Windows 10 could consume 15% more CPU utilization than Windows 7 under comparable workloads.Likewise, services such as Delivery Optimization have repeatedly attracted criticism due to their unnecessary impact on memory, disk and CPU consumption.Most recently, Microsoft published an article suggesting that 32 GB of RAM should be considered a “future-proof” configuration for gaming. The article was later removed.In the current scenario, I still agree with the number, not because modern software is becoming more powerful, but because it’s becoming less efficient, and nobody seems interested in fixing that.When operating systems, browsers, launchers, background services, telemetry pipelines, and web-based applications collectively consume more resources every year, recommending more RAM becomes the path of least resistance. It is almost a joke now. The implicit message is always the same: the problem is your hardware, not our software.This is everywhere. Apple’s Calculator leaked exactly 32 GB of RAM. Windows applications leak memory at the same scale.But the industry has already made its choice.The industry has quietly stopped asking why software requires so many resources and simply assumes hardware will continue scaling and compensating for bad software engineering. At this point, it’s just: generate slop, ship it, repeat. Ship broken, ship slow, as long as it ships. Optimization became optional over the years. There’s no penalty for bloat, no reward for efficiency. The consequences are finally showing.Almost every day, somewhere online, someone is describing their experience with Windows as heavy, bloated, or simply slow, regardless of whether they are running high-end or low-end hardware. Despite how common these complaints are, it is surprisingly difficult to find studies that attempt to measure them properly. Most discussions quickly become anecdotal:“Windows feels slower than it used to.”“Windows 11 is the fastest version of Windows yet.”“Tweaks improve performance.”“Tweaks do nothing.”<br>Everyone seems to have an opinion. Very few people actually measure what they are talking about.This article started as a personal optimization project for my laptop, but eventually became an attempt to answer a simple question:Can my Windows performance issues be concretely demonstrated?<br>The traces give us the answer.The following videos compare the user experience of a freshly updated, unmodified default installation against the Optimized+ configuration, running on the exact same hardware. These captures were made right after rebooting.Note: Optimized+ combines the Optimized scripts (which disable unnecessary services and tweaks system settings) and the Optimized+ script (which takes it further by disabling Update, Defender, and Store). Optimized+ is shown rather than Optimized because the usability experience between the two is essentially identical, making a separate video unnecessary.<br>Default Windows<br>Your browser does not support the video tag.As you can see in the System Informer boot counter, the default Windows took much longer before I could even start recording. The default Windows takes significantly longer to boot — around 3 minutes — and even after that, the taskbar takes another 1 to 2 minutes to appear. With only ~1.6 GB of free memory available even after post-boot, the OS has already consumed most of the available resources. Everything feels artificially laggy, slow to respond, visually sluggish, and imprecise. The kind of experience where you spend more time waiting for the OS than actually using it.Optimized+ Windows<br>Your browser does not support the video tag.The optimized setup, by contrast, is genuinely usable. With ~2.7 GB of free memory available post-boot, the system has actual headroom for user workloads. Replacing the default taskbar with StartAllBack alone makes a huge visible difference — it appears instantly after boot, no delay. Compared to the default experience, it feels smooth....
