> Key: AURORA-1854
> URL: https://issues.apache.org/jira/browse/AURORA-1854
> Project: Aurora
> Issue Type: Story
> Components: Efficiency, Scheduler
> Reporter: Mehrdad Nurolahzade
> Assignee: Reza Motamedi
> Priority: Minor
> Labels: newbie
>
> SLA metrics calculation logic in {{MetricCalculator}} and {{SlaAlgorithm}} causes great churn in scheduler. Profiling shows the burden of calculation can grow as much as 50% of scheduler CPU.
> Create JMH benchmarks for this logic to enable analysis and improvement of these calculators.
