tanx for the answer , indead thats a problem to , i think my best way is to go for multisite and than the db server usage limited to one db , do while it is on a separated server it still offers the full bandwidht of the server to speed up read write on database info , so wenn a lot of users use it at the same time it has a connection of 500 mb to just read the database.. gonne try that , one multisite , on database
post my sultution or findings wenn i have sett it up.
