redmine very slow to respond when submiting issues
I'm using Redmine 0.64.
Every time I submit a issue or issue change there is a delay of 30s between submitting and the response.
In the log I see that the server responds to the POST message with a 302 redirect 30s after it is sent.
I'm pretty sure this is some configuration issue, but I'm not sure how to debug this.
Try to turn off email notification in your config/environment.rb file, then restart your redmine. It should work far better. If you need mail notification, just configure it well before enable it again ;)
PS: I think this issue is in the FAQ.
