F14-11/4: Infuriatingly Fun Performance Puzzles

Track/s: Performance

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 recommendations 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.

He has also consistently established close ties and relationships with the major vendors who create these tools. Mark worked for six years at Microsoft Corporation as a performance consultant and engineer in the Microsoft Services Labs, in the Enterprise Engineering Center and in the SQL Server labs. His efforts to foster the success of Microsoft’s top-tier Enterprise customers was focused on their early adoption of Microsoft products as part of mission-critical operations.
