Infuriatingly Fun Performance Puzzles


You remember George? He’s back to his old tricks! The CPU % was lower than normal on the app server. The calls to the 3rd party were sub-second and not queued. The data sources used were showing consistently increased network utilization, but > 75% available bandwidth.

This entertaining and mentally frustrating session will present several “somewhat common” performance puzzlers and give attendees time to work in small groups to see if they can determine the root-cause for the performance issue. Bonus points will be given for proper recommendation for a fix to the problem. Additional bonus points will be given for recommending what type of testing may have prevented the specific issue.

Session Takeaways:

  • Practice of performance problem-solving techniques.
  • Specific performance problem identification and remedy.
  • Practical application of root-cause analysis skills.
  • Group collaboration on performance analysis.
