Gosu performance best practices

The ways in which you write your Gosu code affects compile-time and run-time performance. As best practices for improving the performance of your code, Guidewire recommends that you always do the following:

• Use the fastest technique for string concatenation
• Consider the order of terms in compound expressions
• Avoid repeated method calls within an algorithm
• Remove constant variables and expressions from loops
• Avoid doubly nested loop constructs
• Pull up multiple performance intensive method calls
• Be wary of dot notation with object access paths
• Avoid code that incidentally queries the database
• Use comparison methods to filter queries
• Use comparison methods instead of the Where method
• Use Count properties on query builder results and find queries
• Use activity pattern codes instead of public IDs in comparisons
• Create single plugin instance
