Hi, I am having some performance problems with Mailman 3 (version 3.3.5) when it sends out a lot of messages to people. We recently migrated from our old Mailman 2.1.x system to Mailman 3.x about 3 months ago. We host about 350 lists with membership counts varying between 10 to 1500 members on some of the lists. I noticed that outbound messages from Mailman to our outbound SMTP are getting delayed up to an hour when Mailman is processing a lot of messages going to lists.
I was wondering if there are good performance tuning tips to be considered for Mailman 3 (i.e. OS, database and/os Mailman Core). I am running the setup on a VM. Here is my configuration for VM and OS:
VM config: ESX 6.7 (CPU: Intel(R) Xeon(R) Gold 6242) 4 CPU 8 GB
SLES 15 SP3 Python 3.9.10 MariaDB 10.5.17 Mailman 3.3.5
Thanks.
