OSBench.exe Real-Time Measurement Tool (Compact 2013)
3/28/2014
OSBench.exe enables you to collect timing samples to measure the performance of the kernel by conducting scheduler performance-timing tests. A scheduler performance-timing test measures how much time is required for a basic kernel operation, such as synchronization. An example of synchronization is scheduling a thread that is waiting on an event that has just been set by another thread. Wherever appropriate, the test runs two sets of metrics: thread-to-thread within a process, and thread-to-thread across processes. If appropriate, you can apply a stress suite while running the test.
OSBench enables you to determine how long it takes to perform the following tasks:
- Acquire or release a critical section.
- Wait or signal an event.
- Create a semaphore or mutex.
- Yield a thread.
- Call system APIs.
You can use the following command-line parameters with this tool.
osbench [-all] [-t test_case] [-list] [-v] [-n number] [-m address]
[-o file_name] [-h]
The following table shows the command-line parameters used with OSBench.exe.
Command-line parameter |
Description |
|---|---|
-all |
Runs all tests. The default setting is to run only those specified by the -t parameter. |
-t test_case |
Specifies the identifier of the test case to run. A separate -t parameter is required for each test. |
-list |
Lists test identifiers with descriptions. |
-v |
Indicates verbose output or to show all measurements. The default setting is to show summary output only. |
-n number |
Specifies the number of samples per test. The default setting is 100. |
-m address |
Specifies the virtual address to write marker values. The default setting is none. |
-o file_name |
Sends output to a comma-separated file. The default setting is to send the output to a debugger message window. |
-h |
Displays a Help screen. |
