The image shows three vertical bar graphs. Each graph has two groups of two bars. The first group in each is labeled "SWITCHOVER" and the second group is labeled "FAILOVER". The legends beneath the graphs indicate that the first bar in each group is data from an Oracle Database 19c setup, and the second bar in each group is data from an Oracle Database 23c setup.

The first graph is labeled "SMALL" with a vertical axis labeled in seconds from 0-90.

The second graph is labeled "MEDIUM" with a vertical axis labeled in seconds from 0-100

The third graph is labeled "LARGE" with a vertical axis labeled in seconds from 0-100

The precise numbers are not given but the 19c bars are much higher (in seconds) than the 23ai bars. Except in the large SWITCHOVER group where they are about the same.
