After upgrade to 3.1.1, my postal is sending less number of emails. Worker > Thread config missing in new config support

[vikasmic]

Describe the bug

I have upgraded the postal server from 2.3.0/1 to 3.1.1

Post upgrade, my postal is just sending 7-8 emails / minute.

In yaml, I am not able to find worker configuration

https://github.com/postalserver/postal/blob/main/doc/config/yaml.yml

quantity: 8
threads: 8

A clear and concise description of what the bug is.

To Reproduce

1. Go to 'https://docs.postalserver.io/getting-started/upgrade-to-v2'
2. Follow the Steps
3. See the sending results.

Expected behaviour

There was a thread configuration in the config file on older version, but its not there on new version and it seems causing a slow email sending issue to my server.

In version 3 (and version 2) the easier way to scale is to add more workers via the --scale argument, I'm not sure off the top of my head if this is documented so not sure what @adamcooke would suggest as the best way for horizontal scaling nowadays.

[adamcooke]

7-8 emails per minute is extremely slow for a single worker. A single worker process can handle significantly more than that on a system that is configured correctly and not sending e-mails to SMTP servers on the moon.

However, the correct way to scale workers on v3 is to use a docker-compose.override.yml file in /opt/postal/install. The old worker configuration never worked well anyway.

version: "3.9"
services:
  worker:
    deploy:
      replicas: 4

Thanks @adamcooke @willpower232

@willpower232 is there a way to set up a thread count as well?

[adamcooke]

No, the thread count on v3 is always 2 for now.
