Parallelism

Concurrency

• Best for visualizing thread parallelism on available cores, finding areas with high or low concurrency, and identifying serial bottlenecks in your code
• Provides information on how many threads were running at each moment during application execution
• Includes threads which are currently running or ready to run and therefore are not waiting at a defined waiting or blocking API
• Also shows CPU time while the hotspot was executing and estimates its effectiveness either by CPU usage or by Threads Concurrency
