Top 5 Items to Help Improve SharePoint Performance

The following are five items to help improve SharePoint performance:

1. Client-side processing and data requests: The SharePoint modern experience utilizes client-side processing and the Microsoft 365 CDN to improve performance.
2. Optimizing network connectivity: Network optimizations from the Microsoft infrastructure use the tuning Network Interface Card (NIC). Coupled with custom drivers these take advantage of the Microsoft Global Network, and assessing network connectivity in the Microsoft 365 admin center.
3. Avoiding common mistakes: Mistakes such as iterating through SPList items, requesting too much data from the content database, memory leaks with SPSite and SPWeb, and using index columns that do not necessarily improve performance.
4. Storage improvements: These include upload, download, and content interaction.
5. Performance monitoring tools: Using performance monitoring tools such as Dynatrace, which offers unique reports based on problems in the environment, assists in troubleshooting problems affecting various SharePoint servers, databases, and the network, and provides proactive alerts to notify admins about any bottlenecks.
