Performance Tuning: A Process, Not Just a Tool
Summary
Every day, businesses face multi-million dollar losses due to inadequate application testing plans and over-reliance on automated testing tools. Without a comprehensive understanding of IT systems, many fail to see the bigger picture. Meanwhile, the market continues to flood with new automated tools.
The Automation Dilemma
The internet is filled with ads for software promising to:
- Analyze application response times from a user experience perspective.
- Provide end-to-end application monitoring.
- Simulate user experiences with precise load testing.
- Automate performance analysis and troubleshooting.
While these products suggest that IT management seeks to automate all aspects of network and application performance, it begs the question: Can we trust automation to monitor itself? It's akin to asking a fox to guard the henhouse. Who monitors the monitoring tools when they’re just another set of applications? This creates a cyclical problem.
The Human Element
Tools are meant to be used by skilled professionals. Relying solely on automation assumes one potential failure can catch another. Often, companies place under-skilled staff in these roles, expecting the tool to self-manage or default settings to suffice?"a Catch-22 scenario.
Experience and expertise cannot be removed from this equation. Even when using automated tools, the skill level of those configuring and managing these tools is crucial for success.
Common Pitfalls
Several issues often arise:
- Automated tests designed by business users and application experts often lack understanding of network, OS, and TCP/IP intricacies. This can result in testing non-existent problems and overlooking real issues.
- Testing spans multiple departments, wearing down staff who may rush to complete the task, accepting any outcome.
- Success in testing doesn’t guarantee real-world performance.
- Ongoing performance problems lead to users complaining to managers instead of filing tickets, creating a gap between perceived and reported issues.
The Solution
The most effective approach to troubleshooting network and application performance is forming a Network & Application Performance Analysis Team. This team, a highly skilled group of individuals, examines all component factors such as:
- Servers
- Directory Services
- Operating Systems
- TCP and other protocol issues
- Workstation configurations
- LAN and WAN issues
- User skills and training
- Database optimization
- Application interactions
- Server consolidation/virtualization issues
Collaboration with application and database experts is crucial. These teams often gain a comprehensive understanding of the application from the ground up.
Effective Resolution
By working alongside users, network staff, and application teams?"and utilizing tools like Sniffer, Ethereal, and Wireshark?"these teams consistently identify and resolve problems. The primary goal is always to achieve resolution through human insight and analysis.
