I am using inline diff (6.x-2.3) to highlight changes between two revisions created with CKEditor. When I would like to highlight changes in large nodes, the system runs into a PHP timeout error (max_execution_time exceeded) without highlighting the changes. This only happens in large nodes with many changes. Otherwise, displaying changes inline for smaller nodes or a 'simple' comparison of selected revisions (even of large nodes with many changes) via revisions tab runs very quick. I guess the performance consuption for displaying changes with inline diff increases exponentially according to the size of a node and its number of changes.
Increasing the max_execution_time parameter up to 10 minutes is definitely not a solution. Has anyone an idea how to present highlighted changes inline to users for large nodes with many changes? Thanks
