> More information: <https://manned.org/mbw>.
|
|
|
|
- Run 3 memory bandwidth tests with 512MB size:
|
|
|
|
`mbw -n 3 512`
|
|
|
|
- Run 3 memory bandwidth tests with 512MB memory size, output only statistics, not averages:
|
|
|
|
`mbw -n 3 -q -a 512`
|
|
|
|
- Run memcpy test 3 times with 512MB size, only display statistics:
|
|
|
|
`mbw -n 3 -q -t{{0}} 512`
|
|
|
|
- Run the memcpy test 10 times with 1024 byte blocks allocated 8192MB of memory:
|
|
|
|
`mbw -n 10 -q -t{{2}} -b 1024 8192`
|
|
|
|
- Run dumb test with 2048MB size, output only statistics, run forever:
|
|
|
|
`mbw -n 0 -t{{1}} -q 2048`
