Hello,

There is. The largest directory I have on my machine has around 18k
files (~5GB) and the penalty is around 20ms. I've run the tests for both
functions in standalone Emacs session started using 'emacs -Q'. Below
are the profiling results:

Function Name     Call Count  Elapsed Time  Average Time
--------------------------------------------------------
dired-revert-new  10          5.2096629750  0.5209662975
dired-revert-old  10          5.051716523   0.5051716522

dired-revert-new  25          11.843308944  0.4737323577
dired-revert-old  25          11.391448779  0.4556579511


Please let me know if that's too high so we can find another way.
