Brodcast Email Segment Take Too Long

Your software
My Mautic version is: 4.4.9
My PHP version is: 8.0.28
My Database type and version is: 10.3.38-MariaDB-0ubuntu0.20.04.1 - Ubuntu 20.04

Your problem
My problem is:

I broadcast email segments to 36K emails, it took about 16 hours to complete. I monitor the email queues in /var/spool.

I set my Email Settings Configuration

Message limit for queue processing: 180
Recovery timeout for resending failed messages: 900
Clear timeout for deleted failed messages: 1800

Cron Job:

mautic:emails:send - Every 5 minutes
mautic:broadcasts:send - Every 5 minutes

Server Configuration:
VPS S SSD 4 cores 8 GB 200 GB (100% SSD)

How do I resolve the issue? Do I need to upgrade the server or make any modification on email setting configuration?

Sending via Amazon SES with 34 emails per second spec.

Appreciate your guys help
