OK, this is good to know, thanks.

No, I don't. I don't think we have ever heard about problems with
these particular volumes. Which is why I suggested to run this slow
operation under perf, which will allow you to produce a profile of the
code, and hopefully will show us which part of the code is the
bottleneck. I don't think we can make any progress here unless we
understand which parts of the code are slow when opening files on
Truecrypt volumes.
Another, less convenient method is to step in a debugger through the
code in find-file and its subroutines, and see which part(s) there
take such a long time. Presumably, if this takes minutes, you should
be able to identify the calls that take such a long time.
As a "leap of faith", how about timing the following, after starting
"emacs -Q":
M-: (insert-file-contents "SOME-FILE") RET
where SOME-FILE is a file on a Truecrypt volume. Does the above take
an abnormally long time, or is it as fast as when you do the same with
a file on any other volume?
