Re: address@hidden: Poor performance over DSL link]

[Richard Stallman]

    If you don't need X Input Methods (XIM) for entering text in some
    language you use, you can improve performance on WAN links by
    configuring Emacs with option `--without-xim'.  Configuring Emacs
    without XIM does not affect the use of Emacs' own input methods, which
    are part of the Leim package.

Can we add a run-time feature to Emacs to disable the use of them?
Would that get the same speedup?
