Interactivity is still worse under ULE. It's quite noticeable and I tested it on two SMP boxes by running two simple loops in kind of: for ((;;)); do let $((4+4)); done # this is bash specific The loops ran under nice +20. Typing in the xterm is jerky, characters will not show up immediately, but in small "bursts". I mean that about three characters typed in will show up immediately, then small pause happens and a burst of characters (which queued up in the pause) will show up. This is annoying. Starting up xterm takes more time as well, but I can live with that. -- Vallo Kallaste
