Temporal isolation or performance isolation among virtual machine (VMs) refers to the capability of isolating the temporal behavior (or limiting the temporal interferences) of multiple VMs among each other, despite them running on the same physical host and sharing a set of physical resources such as processors, memory, and disks.
Performance is a measure of the results achieved. Performance efficiency is the ratio between effort expended and results achieved. The difference between current performance and the theoretical performance limit is the performance improvement zone. Another way to think of performance improvement is to see it as improvement in four potential areas:
The objective of Focused Improvement is to assure that the equipment maintains a peak performance all the time. "The fact is machines do virtually 100 percent of the product manufacturing work. The only thing we people do, whether we’re operators, technicians, engineers, or managers, is to tend to the needs of the machines in one way or another.
Process isolation can be implemented with virtual address space, where process A's address space is different from process B's address space – preventing A from writing onto B. Security is easier to enforce by disallowing inter-process memory access, in contrast with less secure architectures such as DOS in which any process can write to any ...
Site isolation was considered to be resource intensive [5] due to an increase in the amount of memory space taken up by the processes. [30] This performance overhead was reflected in real world implementations as well. [31] Chrome's implementation of site isolation on average took one to two cores more than the same without site isolation. [5]
Performance improvement plans, common at large companies, are a way to formally tell workers they need to improve, and being put on a PIP is commonly understood as a step toward termination.
a part that does not benefit from the improvement of the resources of the system; a part that benefits from the improvement of the resources of the system. An example is a computer program that processes files. A part of that program may scan the directory of the disk and create a list of files internally in memory.
Feedback: The core principle of continual process improvement is the (self) reflection of processes; Efficiency: The purpose of continual improvement process is the identification, reduction, and elimination of suboptimal processes; Evolution: The emphasis of continual improvement process is on incremental, continual steps rather than giant leaps
