All Implemented Interfaces:

junit.framework.Test

Direct Known Subclasses:

BenchmarkJournalWriteRate.BenchmarkBlockBasedOptimium, BenchmarkJournalWriteRate.BenchmarkSmallRecordOptimium, BenchmarkJournalWriteRate.BenchmarkSustainedTransferOptimium

Enclosing class:

BenchmarkJournalWriteRate

public abstract static class BenchmarkJournalWriteRate.AbstractBenchmarkOptimium
extends TestCase2

Does N writes of M size data blocks on a pre-extended file using pure sequential IO. Small writes may be used to estimate the maximum throughput for large numbers of small writes. Large writes may be used to estimate the absolute maximum throughput for your platform (OS + disk system).

Note: This test is conducted without the use of a journal. It is bundled in the same source code file so that we can compare the journal performance with the raw IO performance of the platform.
