The reason the server is extremely laggy is because its running too much data for 1 host / server. I feel like the simple and only solution is to upgrade the host from 1 to maybe 2 or 3.

now you think why does Skyblock lag and not other big servers like Hp or Mp lag, its because their game modes /mini games are spread across multiple hosts/servers they have 1 server/host for every mini game therefor running smooth with no lag.
not one big server like mp or hp can run on a single host/server no matter how good the spec's are its simply too much for all that data and another thing is that skyblock has a ton more data then other game modes.
for example mini games- you play them fast and they don't use to much data and the data can even be deleted afterwards

some examples of other servers / types of mini games on them
factions- one huge world which a lot of players play on
then you get to skyblock like a mini game but the data (aka the un used / inactive islands) can't be deleted as it would just be unfair not to mention the huge amounts of lag coming from hoppers and Redstone on each individual servers like skyblock, economy, and classic.

what I'm saying is we have 1 server for skyblock one for economy and one for classic, Skywars, and the hubs
the whole problem isn't because of the hoppers or Redstone but more because noobcrew is trying to run too much data on 1 server / host even I asked him why do we lag but other big servers dont and his response was because they spread there server on multiple hosts.

then there's the cost of running 2 or 3 hosts who knows how much noobcrew pays for use one but if we added another 1 or 2 and did some advertising we could have a way larger player base racking in more money to keep the new 1 or 2 hosts running

 

Advertising would be costly, I think that if we were to start implementing the ad crate keys, it would look to be a much consistent, safer source of income to acquire additional funds. I do like the idea of having multiple hosts but where would we really need to use them at? The skyblocks are all in one world. The only sensible thing I see with using another server is to yeet the mob arena onto one to create less lag, but I'm not sure if it'd be worth the spending.
