Question

I’m trying to lighten the page load, and I was curious what the DB in… :

Completed in 6427ms (View: 6279, DB: 96)

…meant ?

Because 6279 + 96 != 6427ms

Answer 1

Quoting the rails guide:

Completed in 5ms (View: 2, DB: 0) | 200 OK [http://0.0.0.0/items]

This data is fairly straightforward to
understand. Rails uses millisecond(ms)
as the metric to measure the time
taken. The complete request spent 5 ms
inside Rails, out of which 2 ms were
spent rendering views and none was
spent communication with the database.
It’s safe to assume that the remaining
3 ms were spent inside the controller.
