I'm also graphing the balancer/nginx accepts/handled rate which is
constant at 4K/sec - means the flow itself isn't changing a lot.
I'm also graphing the connections scoreboard from nginx and it also
shows x4 drops/rises when switching from 12.1 to 13.0.
Is this a bug/glitch of the 13.3 statistics (seems unprobeble because
nginx shows it too) or is there some other explanation that I don't get ?
In the end this looks like a regression in the end. Considering two
identical servers rented in one datacenter, I have to downgrade 13.x
balancer to 12.2 - I'm unable to find other eplanation to the things
described above. The difference in connection numbers isn't the major
reason; the real reason is the inability to handle the load, and the
most discouraging thing is that I'm unable to measure this inability
using formal metrics: cpu/disk load is okay, no network errors on the
driver layer, no complains in the dmesg or syslog.
