If you control your backends, consider using normal nginx
procedure with configuration reload to re-resolve names instead.
Alternatively, consider using plain http to communicate with
backends, or tuning SSL for faster handshakes (using ECDSA
certs on backends will help a lot).
A perfect solution for your specific case would probably be an
upstream block with "server ... resolve", but this functionality
is only available in nginx-plus
