I agree. But that only explains the time delay, no why Emacs is consuming 100% of CPU, right? Waiting for the network should not consume CPU, unless I'm missing something. Also, Suhail Singh says that there's a significant delay when there are valid symlinks, in which case I don't expect Tramp to issue the same command 15 times, right? I'm sorry to insist on understanding these fine details, but my experience is that without a good understanding of a problem we might devise a solution that is only a partial one. Thanks.
