Redmine

You should consider using async option in notification settings.

Else, the page is rendered only once all the notifications emails have been sent.

Hello:

I have config the "configuration.yml", as below, but it also slow.

production:
delivery_method: :async_sendmail

Less?

The cost time almost the same before.

Thanks your reply.
How may I confirm the async_sendmail is work?

This is my configuration on /usr/redmine-1.2.2/config/configuration.yml

production:
    delivery_method: :async_smtp
    smtp_settings:
    tls: true
    address: "xxx.com.tw" 
    port: 587
    authentication: :plain
    domain: 'xxx.com.tw'
    user_name: xxx
    password: xxx

I also try to use gmail, but the cost time was 29XXXms, still have long time.

production:
  email_delivery:
    delivery_method: :async_smtp
    smtp_settings:
      tls: true
      enable_starttls_auto: true
      address: "smtp.gmail.com" 
      port: '587'
      domain: "smtp.gmail.com" 
      authentication: :plain
      user_name: "xxx@gmail.com" 
      password: "xxx" 

Another Question:
4. The same environment, when I use the "Private" button on "New issue", and choose 5 watcher only. Why the CPU usage is full use between 30 sec. If the system was waiting mail server response, What does the CPU work?

I'd just like to add that I was having a similar problem with async_smtp, causing 500 internal server error and consuming 100% cpu for around 30 seconds. I was using async_smtp against our local SMTP server, both with and without TLS. I was not able to resolve the issue, and had to switch to using async_sendmail (which fortunately was a valid option for me), and everything is fine.

This really seems like an implementation problem with async_smtp.

Switching from delivery_method "smtp" to "async_smtp" solved my problem. Thanks!
