'Our' interactiveness problem is responsiveness under heavy I/O, I have Intel SSD (which has very fast random access times) but when I do some heavy I/O (even merging a snapshot at VirtualBox) responsiveness is a lot worse until that process stops.

I even have a script to automatically 'renice' the most CPU intensive process:
Code:
% cat scripts/renice.sh 

#! /bin/sh

PROCESS=$( top -b 5 | grep -A 5 USERNAME | sed 1d | head -1 | awk '{print $12}' )
renice -n 10 $( pgrep ${PROCESS} )
