Whoa there!
Are we still talking about C++ Mode (or one of the other modes in the CC
Mode family)? How big is your file? Can you characterise it in any way?
For example, does it contain lots of, or big, raw strings?
I noticed yesterday on a C++ test file with a very long raw string, that
although editing copies of a string segment (using iedit) was fast, undo
afterwards was very slow indeed (~1 minute).
So, perhaps your problem is the same as mine. Perhaps you have
encountered a different problem. It seems I have more work to do on this
in any case.
So, details, please!
