What makes you think that SATA is the bottleneck?
As opposed to what? It's the only disk on the system if that's what you are referring to, the vmstat output shows very high IO wait, and as seen above most of the processes are queue runners and almost no network connections (the load is so high that Sendmail actually refuses new connections). but as far as I understand much slower buffered reads than I should expect:

As I suspected. Thanks, --Amos
