A new analytics cluster is suffering performance slowdowns. Logs reveal high CPU and memory use even at moderate demand, but no major software errors are found. Which choice best addresses these recurring slowdowns?
Restart the entire cluster to clear any lingering tasks
Lower the allocated memory to reduce overhead
Upgrade the compute environment to larger instances
Increasing capacity helps manage peak loads and prevents performance bottlenecks that occur when resources are insufficient. Reducing allocation or only adjusting network parameters would not resolve the core performance bottleneck caused by lack of computing power. Restarting the cluster is a short-term workaround and does not address the underlying shortage of available resources.
