As I said in another thread, they need to get 10 times more servers than they think they need. Gox never seems to be up to par, its like they are ALWAYS playing catch up.
They did. In fact, they had much more than that. As they said, in just the last day the number of trades tripled! It's truly amazing that they scaled as well as they did.
Seems like they may have a bottleneck somewhere that adding servers won't fix. High probability that it's in the database, which is pretty hard to scale by just adding servers. But i don't see how the amount of traffic they get should be this much of a problem for them. They should be able buy a powerful enough database server with one or two day's worth of the profits they make (assuming the $100K+ per day profit I saw posted in another thread is true). I've worked on websites that got 1M+ hits per day in traffic spikes, not quite the same type of app as an online exchange, but I know a little bit about performance and scaling.
For the amount of money they make, and the amount of traffic they do, there is simply no excuse. Their public statements don't instill confidence. First they said "you guys have no idea what it's like, come work with us for a day, we can handle DoS attacks, where withstood two at the same time without any lag", then the next day they are down after the maintenance because of a DoS attack.
