# Performance Tuning Engineering
|
||||
## Overall Strategy
|
||||
### Prioritize/Review Ruby 1.9.3, Ruby 1.8.7, JRuby 1.6.7
|
||||
### Run spectrum of exploratory performance tests
|
||||
### Graph results, probably with gnuplot, with HTML wrapper
|
||||
### Select test for profiling
|
||||
### Find where time is being spent
|
||||
### Construct specific performance test
|
||||
### Iteratively tune specific performance test
|
||||
### Iterate selection of test for profiling
|
||||
## Notes
|
||||
### Start with Create/insert, writing comes first
|
||||
### Then Read/find, reading comes next. both findOne and find-cursor
|
||||
### Update is primarily server load with minimal driver load for conditions
|
||||
### Delete/remove is primarily server load with minimal driver load for conditions
|
||||
## Benefits
|
||||
### Performance Improvements
|
||||
### Knowledge of Ruby driver and techniques
|
||||
### Perhaps architecture and design improvements
|
||||
### Lessons transferable to other drivers
