I am not sure if there are two different problems: - the lagginess (repeated freezing for let's say some 100ms) when increasing cache/buf makes the kernel swap too much (which is clearly different from a system that suffers from heavy swapping, far worse) - the complete and final freeze of the GUI. this happens regardless of swap and probably regardless of disk or cpu load.
