That is 1 or maybe 2 second interval.
One thing I am not sure is why 'bi' (disk writes) stays at 0 mostly,
it's the 'bo' column that shows high numbers (reads from disk). With so
many INSERT/UPDATEs, I would expect it the other way around...

Assuming that's the output of 'vmstat 1' and not some other delay,
50MB/second of sustained writes is usually considered 'a lot'.
