I know from your private post that you are using kaio, so this is OK.

You could afford to raise this: say 1500000?
> NUMAIOVPS 1 # Number of IO vps
According to your private post you have substantial aio vp activity, and
io/wkup ratio of 2.0. You shuld add at least 3 aio vps and get that io/wkup
ratio down to 0.5-ish.
