OSBench.exe (Windows CE 5.0)
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.exe 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] [-ttest_case] [-list] [-v] [-nnumber] [-maddress]
[-ofile_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. |
| -ttest_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 the summary output only. |
| -nnumber | Specifies the number of samples per test. The default setting is 100. |
| -maddress | Specifies the virtual address to write marker values. The default setting is none. |
| -ofile_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. |
