SQL Server services set to Delayed Start - Why?

Microsoft made the change to set SQL Server services to Automatic (Delayed Start) by default in SQL Server 2022 to improve the overall startup performance and reliability of the system. Here are some key reasons and benefits:

Reasons for the Change

3. System Resource Management: Delayed Start helps manage system resources more efficiently during the boot process. It allows critical system services to start first, reducing the competition for CPU and memory resources.
4. Avoiding Conflicts: By delaying the start of SQL Server services, it minimizes potential conflicts with other services that are starting up simultaneously.
5. Improved Boot Times: This approach can lead to faster overall boot times for the operating system, as it spreads out the load of starting services.

Pros of Automatic (Delayed Start)

1. Reduced Startup Load: Helps in reducing the initial load on the system during boot, leading to a smoother startup experience.
2. Enhanced Stability: Reduces the likelihood of startup failures or delays caused by resource contention.
3. Better Performance: Ensures that SQL Server services start after the system has stabilized, potentially leading to better performance and reliability.
