This was just something that I came across and was wondering if anyone has implemented this on a production environment. We do have one particular client where I've noticed excessive swapping and when monitoring this through protop I noticed that the Tomcat java process was the top process that was causing swapping along with the appserver agent processes. When issuing a free -m there is still plenty of available memory available. My thinking is to reduce this value to around 20 to see if this improves %iowait time on the box. The %iowait time on the box pretty much stays between 0.00 and 5.00 but as soon as the machine starts swapping this climbs up to around 20.00 which has a noticeable impact on performance.
