    I am curious as to why on core is running at 100% all the time (if I am reading it correctly). I also have a VPS from another provider and runs at 75-100% but most of the time it is not 100%. Note: I'm in the process of moving everything over here.

    top - 07:51:29 up 63 days, 13:18, 2 users, load average: 0.01, 0.20, 0.71
    Tasks: 49 total, 1 running, 48 sleeping, 0 stopped, 0 zombie
    Cpu(s): 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st

    doulos,

    I think there might be a bit of confusion here. That's not 100% of one core, but rather, 100% of a particular usage type, which in this case is idle time. This means your CPU is 100% available for use :)

    You're fine.
    Idle means your CPU is not doing anything. So your CPU was not used for an average of 99.82% of the time. At it's highest usage your CPU was still 79.17% idle.
    IOWAIT means your CPU was waiting on your drive to provide data. An average IOWAIT of 0 is great.
