Okay, I've decided to start low and increase the children as soon as
I notice performance problems. Is this a good strategy to learn how
many children you need?

I turn off TCP completly and set children to the lowest value:

  listen=udp:name.host.tld:5060
  #listen=tls:name.host.tld:5061
  #disable_tls = 1
  children = 1
  #tcp_children = 1
  fork = yes

...look at this:

  # ps -ef | grep opensips
  osuser 17127 0:00 /pfx/sbin/opensips -P /pfx/var/opensips/opensips.pid
  osuser 17131 0:00 /pfx/sbin/opensips -P /pfx/var/opensips/opensips.pid
  osuser 17128 0:00 /pfx/sbin/opensips -P /pfx/var/opensips/opensips.pid
  osuser 17132 0:00 /pfx/sbin/opensips -P /pfx/var/opensips/opensips.pid
  osuser 17125 0:00 /pfx/sbin/opensips -P /pfx/var/opensips/opensips.pid
  osuser 17130 0:00 /pfx/sbin/opensips -P /pfx/var/opensips/opensips.pid
  osuser 17129 0:00 /pfx/sbin/opensips -P /pfx/var/opensips/opensips.pid

Okay I understand that one of them is the master process and that I
should expect an additional process due to the forking (fork=yes),
but why are there 7 (!) processes being spawned? I do have SRV and
NAPTR records in DNS, can it be due to them?
