Hey guys, Recently I launched a website, to which I sent 50,000-100,000 visitors per day, and I'm having problems when a lot of users come online at the same time (usualy it starts to lag, when I reach 900 online visitors). The dedicated server that I'm using is very good, but the main problem is the databases. I actualy crashed the server several times, and I checked the resources usage, it was very low.. I need a database administrator, who could give me a hand around this? Thank you ..
