After beginning to review and monitor performance, you
need to find out if your objectives are reasonable.
About this task
You should consider questions about the objectives, such
as:
- Are they achievable, given the available hardware?
- Are they based upon actual measurements of the workload?
To measure performance against initial objectives
and report the results to users:
- Identify any systematic differences between the internal
response time, the measured performance data, and the external
response time, what the user sees.
- If the measurements differ greatly from the estimates:
- Revise response-time objectives for the application
- Upgrade your system
- Plan a reduced application workload.
If, however, the differences between internal and external response
times are not too large, you can begin monitoring and tuning the entire
system.
