Optimize your applications with 24×7 continuous thread analysis

Dynatrace

Dynatrace news. Threads enable your application to execute multiple tasks at the same time. This is why threads are often the source of scalability as well as performance issues. If your system is under high load, it can run into thread-locking issues that prevent upward linear scaling of your application. Another potential issue is that too many active threads waste CPU resources, either by over-utilization or by forcing the OS to schedule thousands of threads on a limited set of cores.
