Slow sending speed

Hi,

I am able to send only 90-100 emails per minute. My server config is 8gb, 4 core, ssd drive. But the sending speed is very slow. I tried many combinations nothing is working PNCTL is installed on server. Can anyone help. What could be done to speed it up? Around 1000-2000 email per hour.

Please see the below output. I ran few times to see and noticed it takes 2 minutes to complete 100 emails to send out. Below is the result of first few lines.

@Anand - Put all the output in a file and PM me with it, i need to see the entire output, not just part of it.
Code:
/usr/bin/php -q /var/www/html/wiz/apps/console/console.php send-campaigns --verbose=1 >/var/log/mailwizz.log

Hi All,

Do any one have idea of slow speed. I am able to send only 10k or less than that per hour. It took 2 days to send 300k emails. I have tried many things. Somehow the cron stops working for 5 -10 minutes and starts again. I tested that by refreshing my screen again and again. Hope we have a solution for this?

Hi, I am not able to fix the speed issue. I have tried many combination and reached maximum volume of 1800/min. I am ok with this speed but the problem is the speed keeps on decreasing. I have also tested that the campaign send email fastly when we increase parrallel process. But with high number of parallel process it takes 5-8 minutes to create batches and then 2-3 minutes to send email. This is really very slow speed. With time the sending time increases for creating batches upto 30 minutes. It is also eating up cpu and ram upto 7 GB ram and CPU utilization upto 95% while creating batches. I understand it also depend on latency of SMTP server but with same server config. This is happening for only 1 campaign. Can anyone give me a expert advice on this or MWZ work this way only?
