Likewise scrolling, changing windows etc. is very sluggish. I have a 12/5 Mbps cable line between work/home with usually 8-12ms ICMP rtt. Plenty of available bandwidth and CPU. Emacs feels a lot mot snappy and is usable when starting 'emacs -xrm '*verticalScrollBars: off'. I found the following (old) bug report in emacs bug database that probably describes this bug: http://debbugs.gnu.org/cgi/bugreport.cgi?bug=6429 When googling 'emacs ssh latency' there seems to be more people having this problem and the prevalent advise was to use use server fonts and not client fonts. I tried to compile emacs with '--without-xft' but with no visibly speedup. http://groups.google.com/group/gnu.emacs.help/browse_thread/thread/8bf4914f3a7ae7e5 http://groups.google.com/group/gnu.emacs.help/browse_frm/thread/bd7e102326bec6b2/dd8706c921a0ef8c?tvc=1#dd8706c921a0ef8c Kind regards, Ole Bjorn Hessen --- In GNU Emacs 23.2.1 (x86_64-unknown-linux-gnu, GTK+ Version 2.10.4) of 2011-03-03 on asol1.nm1.telenor.net Windowing system distributor `The X.Org Foundation', version 11.0.10707000 configured using `configure '--prefix=/local/net/arch/linux_x86_64/encap/emacs-23.2'' Important settings: value of $LC_ALL: nil value of $LC_COLLATE: nil value of $LC_CTYPE: no_NO.UTF-8 value of $LC_MESSAGES: nil value of $LC_MONETARY: nil value of $LC_NUMERIC: nil value of $LC_TIME: nil value of $LANG: en_US.UTF-8 value of $XMODIFIERS: nil locale-coding-system: utf-8-unix default enable-multibyte-characters: t Major mode: Lisp Interaction Minor modes in effect: tooltip-mode: t mouse-wheel-mode: t file-name-shadow-mode: t global-font-lock-mode: t font-lock-mode: t blink-cursor-mode: t auto-encryption-mode: t auto-compression-mode: t line-number-mode: t transient-mark-mode: t Recent input: C-x C-b e C-x m q C-x k y e s C-x C-g M-x r e c p o r t Recent messages: For information about GNU Emacs and the GNU system, type C-h C-a.
