Sorry, I was confusing your report with another problem.  Please
disregard the above.

AFAIU, your problem happens when you invoke Emacs as a server via
emacsclient.  Can you confirm that the delays happen only between the
time you invoke emacsclient and the time Emacs responds to the client
request?  IOW, once Emacs does respond, is everything working normally
within Emacs, including any file operations you invoke from within
Emacs, like "C-x C-f", "C-x C-s", etc.?  In your original report you
mentioned "file interaction" in general, but later you described only
the interaction with emacsclient.  So I'm now unsure what exactly is
the precise description of your problem.
