Performance and Tuning

• In this course we can only suggest ideas and methods• The application of these ideas and methods is up to you• If anyone finds something that seems to work – tell us,

so we can incorporate the ideas

Performance and Tuning

• A lot of what we teach here is heuristic – we tried it once (or twice) and it works

• But a large amount comes from the engineers and comes under the heading of “well this should work this way!”

• If this doesn’t happen in the field – let us know – and we will try and find out why
