|
.SH NAME
|
|
stressapptest \- stress test application for simulating high load situations
|
|
.SH SYNOPSIS
|
|
.B stressapptest
|
|
.RI [ options ]
|
|
.SH DESCRIPTION
|
|
This manual page documents briefly the
|
|
.B stressapptest
|
|
command.
|
|
.PP
|
|
\fBstressapptest\fP (unix name for Stressful Application Test) is a program that
|
|
tries to maximize randomized traffic to memory from processor and I/O, with the
|
|
intent of creating a realistic high load situation in order to test the existing
|
|
hardware devices in a computer.
