Criticism
Some publications do not recommend using object pooling with certain languages, such as Java, especially for objects that only use memory and hold no external resources. Opponents usually say that object allocation is relatively fast in modern languages with garbage collectors; while the operator new needs only ten instructions, the classic new - delete pair found in pooling designs requires hundreds of them as it does more complex work. Also, most garbage collectors scan "live" object references, and not the memory that these objects use for their content. This means that any number of "dead" objects without references can be discarded with little cost. In contrast, keeping a large number of "live" but unused objects increases the duration of garbage collection. In some cases, programs that use garbage collection instead of directly managing memory may run faster.

Famous quotes containing the word criticism:
“Homoeopathy is insignificant as an art of healing, but of great value as criticism on the hygeia or medical practice of the time.”
—Ralph Waldo Emerson (1803–1882)
“The aim of all commentary on art now should be to make works of art—and, by analogy, our own experience—more, rather than less, real to us. The function of criticism should be to show how it is what it is, even that it is what it is, rather than to show what it means.”
—Susan Sontag (b. 1933)
“It is ... pathetic to observe the complete lack of imagination on the part of certain employers and men and women of the upper-income levels, equally devoid of experience, equally glib with their criticism ... directed against workers, labor leaders, and other villains and personal devils who are the objects of their dart-throwing. Who doesn’t know the wealthy woman who fulminates against the “idle” workers who just won’t get out and hunt jobs?”
—Mary Barnett Gilson (1877–?)
