Solve the problem of slow write operation Redmine

It used to be run using Redmine directly at the beginning of the Webrick server, and later, in order to improve performance, the use of Nginx+passenger to drive Redmine, the access speed is much faster, but when new problems or update problems become very slow, I thought it was not configured well, and then searched the Internet, and found that it was mentioned because the message was sent when a new issue and update problem occurred, and it was synchronized, that is, it will not be returned until the message is sent successfully. It really dawned on me, so I found a solution to change the way the message was sent to an asynchronous operation:

1. Enter the config directory under the Redmine directory;

2. Editor Configuration.yml;

3. Locate Delivery_method:: SMTP, Change SMTP to ASYNC_SMTP, save exit;

4. Restart the Nginx service;

After completing the above steps, reopen the Redmine, create a new problem and edit the issue after the submission of the swish came out
