Analysis

Overview

Text performance is still not good enough. The purpose of this task is to improve it and make Sophie usable with large text (see TEXT_PERFORMANCE_R0). At this revision, testing and profiling should indicate bottlenecks that need to be fixed.

Task requirements

• Determine bottlenecks that slow down text performance (describe them in design):
  • Manual testing should help see which regular user operations on text take a lot of time to perform.
  • Automatic testing using performance tests should pin out the most time-consuming pieces of code.
• Suggest solutions or ways of improvement (describe them in design)
  • Provide estimate for how much time is needed for them to be done.
• Implement feasible solutions based on the estimates given and the time available.

Task result

• The Design section of this wiki page
• Source code

Implementation idea

Look at the tests and results from the first revision of this task. The number of characters used in the test might be increased for easier interpretation of results.

How to demo

• Show the better performance by pasting a large text and editing it.
• Run the performance tests written and describe the results.
