How can I make Emacs TRAMP mode faster?
ControlMaster auto in my SSH config, and it is working:
$ time ssh -v debel echo foo OpenSSH_5.6p1, OpenSSL 0.9.8r 8 Feb 2011 debug1: Reading configuration data /Users/jmdeldin/.ssh/config debug1: Applying options for * debug1: Applying options for debel debug1: Reading configuration data /etc/ssh_config debug1: Applying options for * debug1: auto-mux: Trying existing master debug1: mux_client_request_session: master session id: 9 foo debug1: mux_client_request_session: master session id: 9 real 0m0.014s user 0m0.008s sys 0m0.003s
But TRAMP is painfully slow (~3 s file saves), as can be seen in this screencast.
M-x shell works fine, but saving is the real slow down. This isn't the best TRAMP can do, right?
- GNU Emacs 24.1.1 (2012-06-01 build)
- I am running a vanilla Emacs instance (I eval'd a color theme in the video, but that's it).
- The VM is running on my machine.
- I am connecting with TRAMP via
/rsync:user@host:file, but I have tried
scp, and even
rsh, and all of them are laggy.
