FindReplace.ReplaceAll() performs bad for large scripts

SyntaxEditor for Windows Forms Forum

Hello,

FindReplace.ReplaceAll() takes very long time to replace all occurrences of some frequent substring.

We tested very large script file (about 3MB, with >20000 lines), and ReplaceAll took about 30 seconds on machine with intel i7 950 3GHz processor.

Since it is very large script, we turned off intellipropmt and some visualization and editing features in advance.

Additionally, UndoRedo.Undo() also performs bad afterwards.

The version we use is 4.0.0287.

Thanks,
Sergej

Hi Sergej,

We are aware of that issue and unfortunately it is something due to how the document change model is set up and how views respond to changes, and not possible to fix without a major rewrite of a lot of functionality.

The good news is that it is something we really focused on when we created the newer object model in the WPF/Silverlight SyntaxEditor, which can replace all and undo much faster since we have it wrapped up in a single transaction instead of one per change unit. We hope to port the newer design back to WinForms once we have implemented all feature areas found in WinForms that aren't yet in WPF/Silverlight.
