This is perfectly normal. It's a rare x86 machine (read fiber channel) where you don't saturate the I/O or the RAM *long* before you saturate the CPU. Transactional databases are an I/O intensive operation, not a CPU-intensive one. > We are running with shared buffers large enough to hold the > entire database Which is bad. This is not what shared buffers are for.
