The cluster fix for random I/O's is turning out to be a pretty serious performance fix for programs doing a lot of random I/O, like postgres. Not only does it fix the disk I/O performance but I am getting reports that it also reduces the VM load (since it is caching less read-ahead data that is never accessed). -Matt
