You said "top -d .1" was 18%, with 11% user, and konsole at 9%. So that gives:
9% konsole 7% kernel 2% top 0% X server ????
If konsole is well-written, that 9% should drop greatly as konsole falls behind on a busy system. For example, when scrolling rapidly it might skip whole screenfuls of data. Hopefully those characters are rendered in a reasonably efficient way. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
