Following on from my previous post on there’s no such thing as a small change…
Please do not make any changes to a production system – a live system – without first testing for any side effects. For example, please do not read a blog post or a book chapter, and then check your system and find you are using manual memory management – and then just turn on automatic memory management. Query plans may change and performance may be impacted. One of three things could happen:
- Things run exactly the same
- Things run better than they did before
- Things run much worse than they did before
Exercise caution before making changes; test the proposed change first!
