“ULC Semaphore Requests” reports the number of times a user task was immediately granted a semaphore or had to wait for it. “% of total” shows the percentage of tasks granted semaphores and the percentage of tasks that waited for semaphores as a percentage of the total number of ULC semaphore requests. This is relevant only in SMP environments.
“ULC Semaphore Requests” provides the following information:
Granted – the number of times a task was granted a ULC semaphore immediately upon request. There was no contention for the ULC.
Waited – the number of times a task tried to write to ULCs and encountered semaphore contention.
Total ULC Semaphore Requests – the total number of ULC semaphore requests that took place during the interval, including requests that were granted or had to wait.
