The summary is that the author tried to open a remote file and Emacs froze for several seconds. He dived deep into finding out why that was and how to fix it, pointing out how great Emacs's introspection is that one can find solutions to problems like these.

And then two thirds of the way into his essay, he has this:

> More recently, I’ve been very put off by the performance and stability (or lack thereof) of building large scale software via Tramp. This has been sufficient to have me looking out again. On a whim, I installed VSCode for the first time and tried its “remote development” capabilities and holy smokes are they good. Getting up and running was trivial and the performance was great. Saving files was snappy and LSP worked out of the box. What a different experience from my carefully-put-together, half-working, slow Emacs setup.

And then later:

> Improve Tramp performance to match the experience of using terminal Emacs via SSH, or VSCode’s Remote Development.
