NAME
wrbench – tool for measuring i/o write throughput.

SYNOPSIS
wrbench [ –l writesize ] [ –T totsize ] [ dialstring ]

DESCRIPTION
Wrbench tests the write throughput of a given file or network connection by writing totsize bytes of data (default 1 gigabyte) in writesize buffers (default 8192 bytes). Wrbench then prints the amount of time in nanoseconds in the first column and the amount of data written in the second column.

Wrbench can differentiate between files and dialstrings so dialstring can also be an undecorated filename.
