Testing Filesystem Performance with Bonnie++

[Igor]

Bonnie++ is a benchmark utility designed to test performance of hard drives and filesystems by simulating various types of disk I/O. Bonnie++ may be used to test local disks as well as network-mounted filesystems. It is recommended that you reboot your server in single-user mode (with network support, if necessary) to avoid resource contention that may skew the benchmark results. For more reliable test results, it is further advised that the amount of data Bonnie++ writes to the filesystem be at least equal to twice the amount of installed RAM...
