Michael, Dmitry,
- I think it is not the best idea to search in files and directories
visited through tramp (does internal grep call have an optimized
version for that?).
- I believe what saving buffers before operation involves more traffic
then checking for modification time.
- Also if I remember correctly I saw some inflating transcoding while
copying files into local machine using tramp (that's why I prefer
using tar/ssh/untar or scp over dired tools for copying files
between machines) - aggressive traffic optimization is not always
used.
- When I trying to type something in buffer visiting modified from
outside file I am prompted to confirm my intention (really edit the
buffer?) - if I'm not wrong, it should involve some network
activity.
So does the time modification checking give so much overhead? I found
the synchronizing of search results in xref buffers with buffer
contents (when you passes through an xref) very comfortable. It might
be more confusing when user clicks to xref and jumps into non-matching
text area.
Best regards,
Andrey Petrov.

In general, this is correct. But verify-visited-file-modtime is
different. Its task is to check, whether the buffer's known file
modification time is still valid; it could have changed on disk due to
external changes or so. That's why it cannot use the Tramp cache.
Best regards, Michael.
