I'm really trying to understand the Cache Churn charts.
i'm looking at a chart which has been split by volume. The volume with the highest cache churn has 50% cache churn for small IO during business hours. The same volume has 71% cache churn for large IO during business hours. How should i interpret those charts?
The resource utilization chart confuses me a little as well, it shows 5% cache usage, but 5% of what actually?
