  • Performance Testing


  • Performance bottlenecks
  • memory leak

The basic symptoms of memory bottlenecks that affect application performance are -

  1. Memory leak
  • Memory usage slowly increases over time
  • Performance degrades
  • Application will freeze/crash requiring a restart
  • After restart application is running fine again, and the behavior continues
  1. Excessive memory footprint
  • Application is slow to load
  • After load, other application runs slower than expected
  1.  Inefficient allocation
  • Application performance suddenly degrades and then recovers quickly
  • % Time in GC Statistic in PerfMon is greater than 20–30%
