I don't know about you guys, but I normally use aternos to create smps where there are like 6+ people (it's always a school smp), and there would always be an opening day where people will join for the first time and it would be like the whole list of players. But, of course with so many people on an opening day (especially opening hour), it gets really laggy. REALLY LAGGY, and I'm sure you know what I'm talking about. I've been a part of so many occasions where people would die because of lag (maybe just skill issue) and they rage quit, probably never joining the server again saying "this server is so laggy I'm not playing again", but in reality it's just because it happened to be the first day and there were a lot of people. Then, the server would lose a lot of members and eventually die off, so then the owners won't use aternos anymore, or for the time being, which I'm assuming aternos doesn't want.
The whole point of this post is to ask if there's any chance there could be a script that detects the first time there are a lot of people, and allocate a lot more RAM than usual into the server, even past the usual player-scaling RAM (I think there's one at least?). The reason why it should be the first time with A LOT of people, and not just one, is because I, maybe some other people like to set up their server beforehand, and with my modded smp, it took two days to make sure everything was working and balanced.
I honestly doubt this post will even change anything, and I completely understand if this doesn't get put into action, because after all this is a free service, and I seriously thank you for that. (I spent like 5 mins on this so if something isn't clear please ask!)
