| Summary:
List of Anti-Patterns:
- Magic Pixie Dust
- Tune in two days
- Zen Master Performance Tuning
- I Know Microbenchmarks (Measure don't guess)
- More hardware will solve it
- User Acceptance Test does not look like production
- More is not necessarily better
- Tools are too expensive
- Cache resistant
- Write business logic in SQL
- Move to the cloud
- A virtual machine is a suitable gift for every occasion
- Spotting non existing patterns
- Tuning/Coding by folklore
- No stress testing
- The busted benchmark
- More cacheing will solve it
- Don't start by (write) sucking (code)
- No performance targets (no requirements)
- We will fix it later
- Loop programming
- Bad / wrong framework idioms
- A fool with a tool is still a fool (with a tool)
- Throw an execution profiler at it
- Excessive logging
- Slavish translation of requirements into code
|
| Recommendations:
Countermeasures
- Plan for performance
- Benchmark
- Measure don't guess
- Teach performance
- Test for performance
- Performance requirements
- Performance tune the requirements
- Increase information intensity in logging (not human readable)
- KISS
