That I do already, of course.

Currently, I try to avoid flushing data mostly. In fact, flushing
happens file-wise or directory-wise only, when the file or directory
changes. And also in `revert-buffer'.
What I'm thinking about is using a time-stamp for cached data. Then one
could introduce a user option `tramp-cache-ttl', which is set to the
number of seconds a cache entry shall be kept. `nil' means no flush (as
it is today); 0 means no caching at all.
A value of 5 would have already benefit, because usually there are
several calls of, for example, `file-attributes' during a short time,
because of more complex operations.
