Quite low load. That machine should not have any trouble to keep up.

What is your peak load?

In the snapshot from the cachemgr there was plenty of resources left. No
obvious sign of shortage.

Hmm. maybe you are running out of ports or some other socket resources.
What is the output of:
 netstat -n | wc -l
 netstat -n | grep SYN_R | wc -l

If the first is more than ~2000 then you need to tune
/proc/sys/net/ipv4/ip_local_port_range to allow the use of a larger
range of ports.

If the second is larger than ~80 (not very likely unless you have a lot
of high latency clients), then you need to tune up
/proc/sys/net/ipv4/tcp_max_syn_backlog.
