It's all about the build up... If the server will have unbalance or corruptions, Server will not have more than 40-50 players max and it will be closed..!!!! On the other hand if you're gonna be serious as an Admin and doing the build up well, everyone will join for sure and maybe the server will grown up faster... Most servers are running as low rate but for High Five client, not for Interlude one because H5 projects(At least most of them) are balanced and up to date... with codes etc.. An example of High Five Low Rate: The upcoming server TheBattle.club they spend time to make this low rate server in High Five Client and it's a risk to do it though.. Because you never know the result of that build and if they will get population or not, Also Most of the visitors count the designing as part of the success(cool website view etc etc)... That's why most of the owners are paying for Designers to get the "most Cool and viewed Design ever"... Success IG = Populated... Fail IG = Locker and that's all folks.
