There is another tool that says how much time is used on each zone or
call. Ah, a profiler. Maybe thousands of calls to the same function is
the issue, or maybe not because the i/o is cached.

But I don't remember how to use a profiler in Linux this instant.

If it were C-code, no problem, but it's PHP. Regardless, it's not so
important how much time is spent where, it's about reducing the time
from 4 seconds to 1 second.
