Start a server with the symfony demo app:
(cd code/base && composer install) && \
sudo docker-compose up
Then open http://localhost:8080/
Things I've tried:
Reset opcache:
curl http://localhost:8080/?reset=1
Simulate a deployment:
(cd code && ts=$(date +%s) && rsync -a base/ $ts/ && rm -rf $ts/var/cache && mkdir $ts/var/cache && chmod 777 $ts/var/cache && rm -f current && ln -s $ts current && curl http://localhost:8080/?reset=1)
Stress the server while doing any of the above:
ab -n 10000 -c 100 http://localhost:8080/en/blog/
