[snip] what would you think is a good number of users hitting the site before you get a noticable performance drop? is there benchmark? if i can only promise 1000 all hiting the site at once, could the client do better elsewhere? is some hosting better known for handling high demand? [/snip] Two. j/k Really this depends on the server setup and bandwidth available to the server and several other things. If 1000 folks are expected to send a request all at the same time there might be a slight lag, but so many factors influence this that it would foolish to posit an answer.
