the class FvmBenchmark method testDB.

/**
 * The following test case benchmarks database performance. It maximizes database read/write and
 * minimizes cache usage.
 *
 * <p>It simulate the situation where there are <code>X</code> blocks, each of which contains
 * <code>Y</code> transactions. Each transaction reads/writes one storage entry of an unique
 * account. This whole process is repeated <code>Z</code> time.
 *
 * <p>There will be <code>X * Y</code> accounts created. Trie serialization/deserialization is
 * expected to happen during the test.
 *
 * <p>NOTE: Before you run this test, make sure the database is empty, to get consistent
 * results.
