We have very large SES limits (500/second, 10,000,000/day) and are trying to send out a newsletter to around 400,000 users right now and Sendy is barely crawling along. In 2 hours, it has sent only 7,500 according to the sending stats in the sendy administration area.
What is the problem here? This is a very powerful dedicated server backed by a very powerful database server. We are sending via cron, and I just don't understand why it's going this slow.
Any advice would be appreciated, as we cannot continue to use this software at this speed. We will have to go back to our custom solution that we used prior to Sendy.
