If the performance of a single CPU is 1, then the performance P of a multiprocessor containing
n these CPUs is expressed as:
In this formula, a is a constant which expresses the overhead. For example, if a = 0.1 and n = 4, then P 3, so the performance of a multiprocessor consis[r]

In a single data structure, the GiST provides all the basic search tree logic required by a database system, thereby unifying disparate structures such as B+-trees and R-trees in a singl[r]

The performance loss in this example is due to a a large number of worker threads: since no I/O takes place, one worker thread would be sufficient, b preemp-tive thread scheduling: optim[r]
