  • How big are your databases?

  • We would need more information in order to answer this question (why are the page faults happening: Are you running other software? Is your DB just that big?, etc...)

This means that 1 b times per sec, sql requires access to a memory space that is mapped in the OS, but not yet loaded in physical memory (still on disk) So there are possibly a very high I/o too ("hi" column in "top").

It's difficult to answer how to fix this, I'm no SQL expert, but this is clearly sub-optimal.
