n

An integer specifying the number of semaphore sets available to the broker.

Use Semaphore Sets (-semsets) to change the number of semaphore sets available to the broker. When more than 1,000 users connect to a single database, there might be high contention for the semaphore set. If there is a lot of semaphore contention on a system, using multiple semaphore sets helps improve performance on high user counts.
