Re: Increased Statistics Ratio in Database Load on Performance Insights When vCPU is Exceeded in AWS RDS for MySQL (8.0.42) During Load Spikes

[Hemant Singh]

Hi Support Team,

We recently performed a minor upgrade of our MySQL environment from 8.0.42 to 8.0.46 to address identified security vulnerabilities. The upgrade was completed successfully without any issues.

However, since the upgrade, we have observed performance degradation during peak business hours, resulting in noticeable application slowness. Prior to the upgrade, the server was operating normally and handling peak workloads without any performance concerns.

Given the business impact and criticality of the issue, we would appreciate assistance from a MySQL performance expert to help analyze the situation and recommend the appropriate corrective actions.

Thank you for your support.

We look forward to your guidance.

Thanks,
Hemant Singh
