I've been doing some testing - two tunables I've found (briefly mentioned earlier) that helps immensely is setting /proc/sys/vm/dirty_background_ratio to 1 and /proc/sys/vm/dirty_ratio to 2.

On some of my systems that I've run the test on it reduces latency down to a fraction of a second - on other systems it reduces it from 20+ seconds to less than 10.

Anyone else see similar behaviour with my simple test?
