Hello, I need some assistance, I am running a forum on vbulletin with vbseo, it on dedicated server with host gator (standard server), the traffic is nearly 15,000 visitors per day, the website run smoothly, but when the traffic become more then 20000 then the server gets down. Can someone please suggest me what to do. I have some more website on that server, so do I need to buy extra hosting for other website. Waiting for the reply.
Do you have SSH access to the server? Check how many apache processes are running during peak time: netstat -na | grep ESTABLISHED | wc -l Then verify if it's hitting the set limit in /etc/apache2/apache2.conf and race this limit if possible (only do this when you see that the server has enough resources (use top for example)
What are the specs of the dedicated server? What do you mean by the server 'goes down'? If its only happening with an additional 5,000 visitors per day (3-4 visitors/minute) is causing the server to come to a crawl, I'm thinking all you should need to do is optimize various services on your server so they run optimally. If that is how many visitors you get per day, how about pageviews?
