[qdr] latency test results are complete for 1.16.x branch
The upshot:
* Worst-case results across the board have greatly improved.
* HTTP adapter has gotten slightly slower in requests per second.
Complete results here

.
Next up -- throughput tests using iperf3.
The tests use 'hey' load generator on one machine, and 'nginx' server on
the other.
The two machines are connected by a 40 Gbit/sec network. Receiving machine
has 32 cores, sender has 16.
The tests are: { 1 sender, 10 senders } { TCP adapter, HTTP1 adapter } {
No Router, One router, Two routers, One 2-armed router, Two two-armed
routers } .

By "two-armed router" I mean a router that is using two separate networks.
In the case of the tests in my Scenarios 4 and 5, I use the 40-Gbit network
for inter-router traffic, and the 'normal' 1-Gbit network for communication
between each router and its attached clients.
The concept is that this might reduce congestion, cause a massive increase
in throughput, and shower everyone involved with glory and honor.
Unfortunately there is such a large disparity in speed between these two
networks that I doubt this is a fair test of the idea. Showering of glory
and honor postponed until further notice. Maybe someday I will find some
extra high-speed NICs and cables lying about ....
