During performance testing of software, developers are looking for performance symptoms and issues. Speed issues — slow responses and long load times for example — often are observed and addressed. But there are other performance problems that can be observed:

  • Bottlenecking — This occurs when data flow is interrupted or halted because there is not enough capacity to handle the workload.
  • Poor scalability — If software cannot handle the desired number of concurrent tasks, results could be delayed, errors could increase, or other unexpected behavior could happen that affects:
  • Disk usage
  • CPU usage
  • Memory leaks
  • Operating system limitations
  • Poor network configuration
  • Software configuration issues — Often settings are not set at a sufficient level to handle the workload.
  • Insufficient hardware resources — Performance testing may reveal physical memory constraints or low-performing CPUs.
