Faster replacement strategies typically track of less usage information—or, with a direct-mapped cache, no information—to reduce the time required to update the information. Each replacement strategy is a compromise between hit rate and latency.
A lightweight web browser is a web browser that sacrifices some of the features of a mainstream web browser in order to reduce the consumption of system resources, and especially to minimize the memory footprint. [1] [2] [3] The tables below compare notable lightweight web browsers.
It refers to the average time it takes to perform a memory access. It is the addition of the execution time for the memory instructions and the memory stall cycles. The execution time is the time for a cache access, and the memory stall cycles include the time to service a cache miss and access lower levels of memory. If the access latency ...
Underclocking, also known as downclocking, is modifying a computer or electronic circuit's timing settings to run at a lower clock rate than is specified. Underclocking is used to reduce a computer's power consumption, increase battery life, reduce heat emission, and it may also increase the system's stability, lifespan/reliability and compatibility.
Moreover, as the goal of page replacement is to minimize total time waiting for memory, it has to take into account memory requirements imposed by other kernel sub-systems that allocate memory. As a result, page replacement in modern kernels ( Linux , FreeBSD , and Solaris ) tends to work at the level of a general purpose kernel memory ...
If the memory access time is 0.2 μs, then the page fault would make the operation about 40,000 times slower. Performance optimization of programs or operating systems often involves reducing the number of page faults. Two primary focuses of the optimization are reducing overall memory usage and improving memory locality.

This has two aspects: the amount of memory needed by the code (auxiliary space usage), and the amount of memory needed for the data on which the code operates (intrinsic space usage). For computers whose power is supplied by a battery (e.g. laptops and smartphones ), or for very long/large calculations (e.g. supercomputers ), other measures of ...
