It's really simple actually. Gab is a fork of Mastodon and most of the 'mastodon' reffs are removed from the code but the main app is the same.
Gab runs just like Mastodon on 3 different services:
1. - gabsocial-web (mastodon-web) -- this delivers the front app for users to login (web and stuff)
2. - gabsocial-sidekiq (mastodon-sidekiq) -- this process all the actions from users local and in the fediverse (post, follow, favourite etc)
3. - gabsocial-streaming (mastodon-streaming) -- this is the API part that takes care of the endpoint for applications for example
I think #Gab has troubles with the sidekiq part (2) if you have that much users to take care of it will generate a lot of actions(!!) so you need to spread this to multiple servers to decrees loads and get all actions done (within reasonable time ofcourse)
I hope this clears up things a little!
