Bottleneck on connection accept rates

I'm running the epel build of varnish on CentOS 7 inside a kubernetes pod (docker container).

# rpm -qa | grep varnish
varnish-4.1.5-1.el7.x86_64
# uname -a
Linux media-cdn-2400684925-p137g 3.10.0-514.10.2.el7.x86_64 #1 SMP Fri Mar 3 00:04:05 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Currently I seem to be hitting a bottleneck with connection accept rates in varnish.  Or maybe I have another problem and it's manifesting like this. Commands like "netstat -nt" show many connections to varnish in the SYN_SENT state which is why I think varnish can't keep up with the listen backlog.

I believe I've ruled out the acceptor_sleep scenario (no debug messages that would accompany it are logged), but I'm going to try and disable it explicitly and see if that helps.  I'm also going to try using the accept-filter feature, although I'm not sure how supported it is.  And maybe try reducing timeout_linger.

My goal is to have 1-2K simultaneous connections with an establish rate of 1-2K/second.  Cache miss rate will be 100% so there will be lots of backend connection management going on. Is this a realistic goal?

Below I have examples of param.show + "varnishtop -i Debug" + "varnishstat -1"

I've been assuming that I need roughly one thread per simultaneous client connection.  Is that reasonable or do I need to factor in backend connections too?
