Stooney Posted January 15, 2008 Share Posted January 15, 2008 I have a site where users can bid on items online. The page that displays the list of items and the current bid and bidder uses an AJAX script that queries a database every 3 seconds for the updated bids. This is so the user never has to refresh, as well as for the page the business uses to display the auction on TV. Now with about 100 users viewing this page at the same time, is that too much of a load? That would be about 2,000 requests a minute. (100 users, each user would cause 10 queries per 3 seconds. That's a query for each of 10 items that is displayed). In the future it could get as high as 1000 users viewing. Should I make the users refresh manually and only allow the admins/moderators to use the AJAX refresh method?

fanfavorite Posted January 23, 2008 Share Posted January 23, 2008 If you are requesting a lot of information for the updated bids, I would call another function first that checks to see if a new bid is available. For instance, when the page loads, it has an id of 156. If last bid is still 156, don't refresh bid. If you don't update a lot of information about the bid, then disregard that. As for the server load, that is more something to ask your host about.
