Sorry, didn't realize this is an English mailing list.
To sum it up: the problem is most likely about clients and not the server.
Discrepancy between request time and upstream time usually means that a
client is slow or uses a bad connection.
Basically, this is OK unless you have the only server out of many with
this problem.
This in turn may mean that the problem is with that server's network
connection.
Regards.

Проблема, скорее всего, в клиентах.

columns: wallclock time, request time, upstream_request_time,
upstream_connect_time, upstream.
Please, help me diagnose this problem further as I stuck. This is
subset where request_time 50x bigger than upstream_request_time (just
to make subset less noisy). I see request times up to 60 seconds. Can
not tie it to some periodicity. It happens so often that don't see
anything helpful in strace... I stuck... Any ideas?
This is nginx/1.10.2 on FreeBSD 10.3-RELEASE-p7.
