Re-investigating performance of SQL Server Availability Groups on Storage Spaces. Why You Should Always Enable Read-Only Routing

In this post, I am going to take a closer look at the impact of read-only routing on SQL Server Availability Groups performance.

Can SQL Server Failover Cluster Instances run on S2D twice as fast as SQL Server Availability Groups on Storage Spaces? Part 2: Studying FCI performance

It is the second part of my research on SQL Server Availability Groups (AG) and SQL Server Failover Cluster Instances (FCI) performance. Before, I measured SQL Server AG performance on Storage Spaces. Today, I study the performance of SQL Server FCI on S2D, trying to prove that this thing can run 2 times faster than SQL Server AG on Storage Spaces.
