ok, mr smartass, you know damn well just as i do that it's NOT the database itself that is causing it. now stop bitching about the hosting and the used databases. maybe you prefer oracle, fine. they use mysql. mysql CAN handle more than 20 users at the time, they can handle hundred of THOUSANDS of users at the time, that's why NASA uses it as well on some occasions.
it's stable enough, and reliable, and the reason there is a maximum number of users is because they want to reduce server load.
but a smart guy like you could have figured that out as well
