The web that comes with redmine is webrick, and the access is very slow and unbearable. I
read on the Internet that webrick resolves the domain name, but it cannot be resolved, and then go back to the IP after a circle. This is not a waste of time.
The solution is to use mongrel this web.
# gem install mongrel
startup method
# ruby /usr/local/redmine/script/server mongrel -e production -d
to visit again, is it much faster?
