21 * @file datastore/perf_datastore_api.c
22 * @brief performance measurement for the datastore implementation
23 * @author Christian Grothoff
25 * This testcase inserts a bunch of (variable size) data and then
26 * deletes data until the (reported) database size drops below a given
27 * threshold. This is iterated 10 times, with the actual size of the
28 * content stored and the number of operations performed being printed
29 * for each iteration. The code also prints a "I" for every 40 blocks
30 * inserted and a "D" for every 40 blocks deleted. The deletion
31 * strategy uses the "random" iterator. Priorities and expiration
32 * dates are set using a pseudo-random value within a realistic range.
