* @brief performance measurement for the datastore implementation
* @author Christian Grothoff

- * This testcase inserts a bunch of (variable size) data and then deletes
- * data until the (reported) database size drops below a given threshold.
- * This is iterated 10 times, with the actual size of the content stored,
- * the database size reported and the file size on disk being printed for
- * each iteration. The code also prints a "I" for every 40 blocks

* inserted and a "D" for every 40 blocks deleted. The deletion
- * strategy alternates between "lowest priority" and "earliest expiration".
- * Priorities and expiration dates are set using a pseudo-random value

/**
* Target datastore size (in bytes).
- * <p>
- * Example impact of total size on the reported number
- * of operations (insert and delete) per second (once
- * roughly stabilized -- this is not "sound" experimental
- * data but just a rough idea) for a particular machine:
- * <pre>
- * 4: 60 at 7k ops total
- * 8: 50 at 3k ops total
- * 16: 48 at 8k ops total
- * 32: 46 at 8k ops total
- * 64: 61 at 9k ops total
- * 128: 89 at 9k ops total
- * 4092: 11 at 383k ops total (12 GB stored, 14.8 GB DB size on disk, 2.5 GB reported)
- * </pre>
- * Pure insertion performance into an empty DB initially peaks
- * at about 400 ops. The performance seems to drop especially
- * once the existing (fragmented) ISAM space is filled up and
- * the DB needs to grow on disk. This could be explained with
- * ISAM looking more carefully for defragmentation opportunities.
- * <p>
- * MySQL disk space overheads (for otherwise unused database when
- * run with 128 MB target data size; actual size 651 MB, useful
- * data stored 520 MB) are quite large in the range of 25-30%.
- * <p>
- * This kind of processing seems to be IO bound (system is roughly
- * at 90% wait, 10% CPU). This is with MySQL 5.0.
