As a note, when using tmux on a "slow connection" and you "accidentally cat" a large file, it can take minutes for it to catch up to your Ctrl+C, etc.  

Maybe tmux could add an option "only refresh the viewable window" or something similar to mosh, to make "lots of output" fast on slow connections?  Just a thought, cheers!

How old is your tmux?

I don't see a "--version" option, but package says:

tmux.x86_64                                                                                          1.8-4.el7                                                                                     


Thanks!

$ tmux -V

tmux 1.8

Your tmux is extremely old, try a newer version.

OK I tried with git master, it does seem to redraw the screen, but still is not as responsive as mosh, where ctrl+c's come through almost immediately.  FWIW.

mosh has 1) a client and server at each end of the connection and 2) one writer and one reader. this means it doesn't have the same limitations as tmux

in any case is a compromise between speed and responsiveness, within the limits we have. we could probably make ^c more responsive but it would make output slower in the case where you don't press ^c

Hi Roger,

There's nothing stopping you from using tmux through mosh, this is how I use it every day for work.

Also, the  packages for tmux included with RHEL/CentOS are notoriously outdated.  I maintain a repository of the latest tmux release which you can use to stay up-to-date if you wish:


Regards,

Scott
