The whole of it, mostly. I've shown a simple patch which improved
performance a lot, by Michael says it's unmaintainable (IIUC):
I'm not sure wether what I'll say is relevant to this discussion (please forgive me if it is not), but I just wanted to mention that a significant part of "debugging TRAMP problems" in projects like projectile is related to TRAMP's speed.
I always assumed it was due to the fact that checking file attributes over SSH is unavoidably slower than doing it locally, but if TRAMP can be improved for things like `locate-dominating-file` over TRAMP it'd be a huge help.
Kind regards,
Philippe
