In this article, I’d like to compare results of the previous two and find out whether SQL Failover Cluster Instance (FCI) can provide you two times higher performance than SQL Server Basic Availability Groups (BAG).

Can SQL Server Failover Cluster Instance run twice as fast as SQL Server Basic Availability Groups in 2-node cluster? Part 1: Studying BAG performance
I thought: “Hey, why not write an article about BAG performance?” Later, I realized that you need to compare this performance to something else, right? So, I decided to add SQL Server Failover Cluster Instance (FCI) performance measurements. Maybe, I’ll add some SQL Server Availability Groups (AG) measurements at the end; but, let’s see first whether SQL Server FCI can run twice as fast as SQL Server BAG. In this study, I measured BAG performance alone. Now, as we know the scope of the article, let’s move on!
