For example, one can interpret a load average of "1.73 0.60 7.98" on a single-CPU system as: During the last minute, the system was overloaded by 73% on average (1.73 runnable processes, so that 0.73 processes had to wait for a turn for a single CPU system on average). During the last 5 minutes, the CPU was idling 40% of the time, on average.
A memory leak can cause an increase in memory usage and performance run-time, and can negatively impact the user experience. [4] Eventually, in the worst case, too much of the available memory may become allocated and all or part of the system or device stops working correctly, the application fails, or the system slows down vastly due to ...
Establishing that a computer is frequently CPU-bound implies that upgrading the CPU or optimizing code will improve the overall computer performance. With the advent of multiple buses, parallel processing, multiprogramming , preemptive scheduling, advanced graphics cards , advanced sound cards and generally, more decentralized loads, it became ...
The XSAVE instruction set extensions are designed to save/restore CPU extended state (typically for the purpose of context switching) in a manner that can be extended to cover new instruction set extensions without the OS context-switching code needing to understand the specifics of the new extensions.

The Management Engine is often confused with Intel AMT (Intel Active Management Technology). AMT runs on the ME, but is only available on processors with vPro.AMT gives device owners remote administration of their computer, [5] such as powering it on or off, and reinstalling the operating system.
The Linux kernel notably makes wide use of self-modifying code; it does so to be able to distribute a single binary image for each major architecture (e.g. IA-32, x86-64, 32-bit ARM, ARM64...) while adapting the kernel code in memory during boot depending on the specific CPU model detected, e.g. to be able to take advantage of new CPU ...
StatCounter web usage data of desktop or laptop operating systems varies significantly by country. For example, in 2017, macOS usage in North America was at 16.82% [99] (17.52% in the US [100]) whereas in Asia it was only 4.4%. [101] As of July 2023, macOS usage has increased to 30.81% in North America [102] (31.77% in the US) [103] and to 9.64 ...
