db_env_set_pageyield

						#include <db.h>
						int
						db_env_set_pageyield(int pageyield);
					

Description

Yield the processor whenever requesting a page from the cache. Setting pageyield to a non-zero value causes Berkeley DB to yield the processor any time a thread requests a page from the cache. This functionality should never be used for any other purpose than stress testing.

The db_env_set_pageyield interface affects the entire application, not a single database or database environment.
