Bonnie++ is an open source benchmark suite that is aimed at performing a number of simple tests of hard drive and file system performance. As well as Bonnie++ itself and some output filters, the suite provides some other benchmarking tools including ZCAV, which can compare the raw-read performance of different zones on a drive, and gives output suitable for Gnuplot.
This program is used by ReiserFS developers.
Bonnie++ is based on the Bonnie benchmark written by Tim Bray.
- Benchmark how a file system perform various tasks.
- Tests database type access to a single file (or a set of files if you wish to test more than 1GB of storage).
- Tests creation, reading, and deleting of small files which can simulate the usage of programs such as Squid, INN, or Maildir format email.
- Bonnie++ benchmarks the following metrics:
- Data read and write speed.
- Number of seeks that can be performed per second.
- Number of file metadata operations that can be performed per second.
- Includes ZCAV, a program to test raw hard drive throughput by reading the entire data on it a specified number of times.
- Direct IO support.
