For example, to test read performances for 10-bit HD on the partition7:

./sw_io_perf_tool -p 7 -v HDTV -d 10

You may also use sw_io_perf_tool with custom resolutions. For example,

to test read performances for frames with a width of 1600 pixels and a

height of 900 pixels:

./sw_io_perf_tool -p7 -v 1600,900

The command displays the throughput (in MB/sec) and maximum IO

latency detected (in ms), as shown below:

Running Stone+Wire IO Performance Test (Partition 7)

Video: 1 stream(s) of HDTV @ 10bit

Proxy: None

Audio: None

This test will take approximately 11 seconds

*** Read Test ***

Bandwidth: 275.456 MB/s

Frame Rate: 39.351 Frames/s

Max Latency: 335.284 ms

Notes:

■ The command can be run while other operations are ongoing to simulate

how the application will behave under these conditions.

■ The media used by sw_io_perf_tool is allocated and freed automatically.

■ sw_io_perf_tool will not reserve any bandwidth on the storage device.

■ Partitions/Volumes must be properly configured in the Stone and Wire

configuration file.
