Good Morning,

today i updated my replica 3 setup (debian stretch) from version 5.5
to 5.6, as i thought the network traffic bug (#1673058) was fixed and
i could re-activate 'performance.quick-read' again. See release notes:


Upgrade went fine, and then i was watching iowait and network traffic.
It seems that the network traffic went up after upgrade and
reactivation of performance.quick-read. Here are some graphs:

Just wondering if the network traffic bug really got fixed or if this
is a new problem. I'll wait a couple of minutes and then deactivate
performance.quick-read again, just to see if network traffic goes down
to normal levels.

Best regards,
