Hi, I had a nice discussion with tmux maintainers over at https://github.com/tmux/tmux/issues/13 about the tmux 2.0 regression on Cygwin.
Long story short, tmux is trying to read /proc/<pid>/cmdline and /proc/<pid>/cwd for various reasons and for non-Cygwin programs this is quite slow. You can reproduce this easily run cmd.exe inside bash and try to cat /proc/<pid of cmd.exe>/cmdline and see it takes a second long to print "<defunct>". Would be nice to fix this slowdown so tmux can be speedy again. For now setting automatic-rename to off set -g automatic-rename off helps somewhat.
