Computer performance

array data structure that replaces runtime computation with a simpler array indexing operation

effectiveness of a computer system or component (hardware or software) at performing useful work

measure of a computer's processing speed

amount of computational resources used by an algorithm

In computing, memoization or memoisation is an optimization technique used primarily to speed up computer programs. It works by storing the results of expensive calls to pure functions, so that these results can be returned quickly should the same inputs occur again. It is a type of caching, normally implemented using a hash table, and a typical example of a space–time tradeoff, where the runtime of a program is reduced by increasing its memory usage. Memoization can be implemented in any programming language, though some languages have built-in support that make it easy for the programmer to

amount of time for which a central processing unit (CPU) was used for processing instructions of a computer program or operating system, as opposed to, for example, waiting for input/output (I/O) operations or entering low-power (idle) mode

measure of processing speed: the average number of instructions executed for each clock cycle

TechPowerUp GPU-Z (or just GPU-Z) is a lightweight utility designed to provide information about video cards and GPUs. The program displays the specifications of Graphics Processing Unit (often shortened to GPU) and its memory; also displays temperature, core frequency, memory frequency, GPU load and fan speeds.

type of figure of merit describing computer energy efficiency

method of transferring program control to another part of a program

problem of optimising network sockets to handle a large number of clients at the same time

any process whereby computer resources are released from use for further use

In computer science, a task, job or process is said to be CPU-bound (or compute-bound) when the time it takes for it to complete is determined principally by the speed of the central processor. The term can also refer to the condition a computer running such a workload is in, in which its processor utilization is high, perhaps at 100% usage for many seconds or minutes, and interrupts generated by peripherals may be processed slowly or be indefinitely delayed.
