Well, I'm running a similar setup, only Xeon 2.4 dual and running with 300k states, the info so far is:
State Table Total Rate current entries 89976 searches 20496469487 54332.6/s inserts 98362130 260.7/s removals 98272154 260.5/s load averages: 0.87, 0.64, 0.52 00:22:32 39 processes: 38 idle, 1 on processor CPU states: 0.0% user, 0.0% nice, 0.0% system, 0.0% interrupt, 100% idle Memory: Real: 19M/234M act/tot Free: 1780M Swap: 0K/2048M used/tot That load seems to be coming from some cron jobs, since it was around 0.2/0.3 some days ago.
