Ya The Server 3c Lagg maybe cause old version of Sa-mP

Nop,it isnt.
Some servers which are hosted in 3c are having 100's of players online.
But still it wont cause lags,but our does.
It's because our server is having more accounts.

It's also difficult to edit you guys's account because the FTP lags while viewing the accounts folder,once when I went to Simon's house,I saw him getting mad of editing some account.

So it isnt the problem of 3c,its because of more users.
