FYI:

Code:
mysql> show variables like '%long_quer%';
+-----------------+----------+
| Variable_name   | Value    |
+-----------------+----------+
| long_query_time | 0.400000 |
+-----------------+----------+
1 row in set (0.01 sec)

Code:
ubuntu# mytop

MySQL on localhost (5.7.23)                                                                                                    load 0.97 1.18 1.38 2/1855 6627 up 0+21:55:36 [22:20:02]
 Queries: 29.3M    qps:  389 Slow:     0.0         Se/In/Up/De(%):    71/01/06/00 
 Sorts:    663 qps now:  291 Slow qps: 0.0  Threads:    3 (   1/  13) 71/01/06/00 
 Key Efficiency: 100.0%  Bps in/out: 75.9k/25.1M   Now in/out: 55.3k/19.8M

So, after a sampling of nearly 30M queries over the past day or so, no query was found over 0.40 sec.

Will reduce to 0.2 or 0.3 seconds at a later date (the next time I restart mysql) and test again.
