System Response Time Measurement (SRTM)

Description

The System Response Time Measurement (SRTM) utility measures timer delivery latencies using the RTX synchronized clock and timers. It then prints the results.

Source Files

srtm.c gathers thread-level timer latencies (either as a Win32 or RTSS process) and prints out a summary and an optional histogram of results. The timer can also generate a sound on the speaker. This is a useful tool for measuring application-level response time latencies while the system is stressed by other activity, such as disk, network, and GUI IO, and/or heavy processing. Different hardware platforms can also be compared.

Build the Sample

Open the solution in the desired Visual Studio version you wish to build.
Once Visual Studio is open, build the sample in any desired configuration that is available

Usage

srtm | srtm [/?] [/h] [/s] [/1] [/f] seconds_to_sample

Options

/h = Display histogram (in addition to summary)

/s = Turn on sound (square wave driven by timer)

/1 = Use a 10 MS timer period (default is 1 MS)

/f = Use fastest available timer (1MS or better)

/? = help on usage

If no parameters given, default is srtm /h /s /f 15\n

Remarks

The SRTM program can be built as a Win32 .exe or real-time .rtss executable file.
