what i have noticed is as soon as there are 100-125 people logged in, the server starts to lag noticeably.
at about 150 people pretty much everything is very slow to respond, and freezes start to happen fairly often.
by the time 175-200+ are logged in, like during EG, the servers became nearly unplayable.
at this point reloads and browser re-boots are required at least 10 times an hour, with logins taking up to several minutes.
on some of the faster paced servers i play, this dramatically impacts efforts to follow calls, be on point for recalc changes, ect.
i don't know what the devil your techs are doing, but whatever it is, they are causing players to leave the game entirely.
in servers i play, we have lost several people due to this problem.
don't believe me? no problem. simply track the numbers over the last 6-9 months, it's pretty clear.
