Yes, I tried even more.

I will be writing data quite constantly in the real scenario
later. So I wonder if increasing WAL logs will have a
positive effect or not: AFAIK when I increase it, the
duration after the max is hit will be longer then (which is
not acceptable in my case).

Could anyone confirm if I got it right?
