I’m interested to know what the future of remove development with emacs might look like. I’m a long time emacs user, and use rust, lsp-mode, magit and projectile heavily. The remote experience with tramp just isn’t very good. I’ve had to work around several bugs that lead to hangs, and even though I’m only ~20millis away from my remote machine performance is pretty bad. I believe I’ve already done everything I can to make it fast (ssh control master, etc.), and I’m still not happy. On the other hand, VSCode (which I’m not familiar with) or IntelliJ make remote development a breeze. I really like how they hide latency, and handle reconnects well. I’ve also tried terminal emacs on the remote machine, but I just can’t deal with the input lag.
It’s remarkable how emacs has been able to adapt over the years, and so I’m interested to hear about some ideas to keep emacs relevant for this usecase.
I may have a few tweaks I can check tomorrow at my work machine, but mine was never that bad. I find the diff is slow and can freeze up for a minute or two if you run a huge multi thousand file diff, but I don’t imagine its that. Have you tried disabling magit-revert mode, or eglot mode? LSP or auto-revert checking the file state are usually culprits of lag for me.
