We recently upgraded from apsose word 17.4 to 18.6 and having big performance hit on that version.
After investigation we found this call is very slow: Document.Range.Bookmarks[processedBookmark.Name] != null in 18.6. I is not possible to replicate this in simple app because of the complexity of the code.
I tried 18.7 and it is same.
I wanted to try 18.8 but we don’t have license for that version yet.
Please provide help.
