How to track speed of email sending?

[Lakjin]

I send a high volume of emails using MailWizz. I have Redis queue setup. It used to take 2-3 hours to send around 500,000 emails. Now, out of the blue, it is taking 12-15 hours. I'm not sure why.

Is there any debugging function of MailWizz which allows me to get reports to what has delayed the sending of these emails? I want to know what is causing the delay to see if I can speed it up.

Thanks!

Hey,

Most likely the database is causing the issue.
You could try https://forum.mailwizz.com/threads/debug-send-campaigns-command.523/ from command line and see exactly what happens while the command runs.

I think I've figured it out -- campaign_delivery_log table is getting extremely large and slowing down queries. I recall you mentioning something about an experimental feature to keep that log small... I am going to try and see if I can get it work.

@Lakjin - Yes, it's the archiving command, worth tested.
