php-fpm optimal config 512Mb droplet with two wordpress

Hello. I’ve an 512Mb ubuntu droplet with 2 virtual servers with wordpress (low number of visits). I’ve optimized nginx, mysql, unnecesary processes… but php-fmp?
i’ve found those recomendated params, are they ok? Thanks!

php-fpm.conf … emergency_restart_threshold = 10 emergency_restart_interval = 1m process_control_timeout = 5s
