I’ve been utilizing SharePoint 2013 on-premise, and it had been functioning smoothly until recently when its performance significantly declined. Within the setup, I’ve configured workflows for task generation and forwarding. Incremental crawling is scheduled daily at 7 PM and typically completes within 5-10 minutes, while full crawling occurs every 4 months. Whenever a task is created or forwarded to a user, an email alert is triggered. Additionally, when an announcement is uploaded to SharePoint, email alerts are dispatched to approximately 70 recipients. The server hosts four sites, equipped with 32 GB of RAM and 2 TB of storage. Currently, the accumulated data consists of around 800 GB of documents/files, totaling approximately 80,000 documents. However, in the past couple of days, the performance has drastically deteriorated. Upon analyzing the log files, I’ve observed recurring warnings.
