Improving Concurrency in Oqtane Scheduled Jobs with SemaphoreSlim
Tuesday, 10 June 2025
This article discusses how to improve concurrency in Oqtane scheduled jobs using SemaphoreSlim, a lightweight .NET threading primitive that controls parallel task execution. In multi-tenant environments with high module workloads (e.g., discussion or quiz modules), uncontrolled parallelism can overload databases or server resources. The solution demonstrates using SemaphoreSlim to throttle concurrent operations, ensuring efficient, isolated, and error-resistant processing. A real-world example from an Oqtane Discussion Module shows how to update statistics across multiple sites without overwhelming the system. Key benefits include multi-tenant efficiency, error isolation, tunable performance, and non-blocking I/O.
