Як перевірити час відклику сайту з командної стрічки linux

curl -s -w %{time_total}\\n -o /dev/null http://site.com.ua/

apache2 + php7 з коробки не запустився в Linux Mint 18

Видає помилку: "Apache is running a threaded MPM, but your PHP Module is not compiled to be threadsafe. You need to recompile PHP"

Вирішення:

sudo a2dismod mpm_event
sudo a2enmod mpm_prefork
sudo service apache2 restart
