How to know the maximum number of simultaneous connections of mysite?

The thread name says it all..

how can i find the maximum possible connection... i mean maximum number of unique visitors my site can survive.. there must be a limit i suppose and if there is, the visitors would get a 404 or what? Guidance would be appreciated

 

It's limited by your hardware and uplink speed, it's hard to determine without more information, once your server reach his maximum resources probably they won't be able to connect to the server.

 

There are a number of limits on different levels that can affect this. The type of service you're running can have an effect on different areas so you would be starting from that.

The operating system has hard-coded and configurable limits for things such as the number of files a user can open at once or the number of processes that can be run at any given time. These can be increased or decreased, depending on how powerful your system is (check out the ulimit command and /etc/security/limits.conf).

Then, your web server or application will have it's own limitations. For example, Apache, by default, is configured to handle a max of 150 connections, after which, any new connections will be put on a "waiting list". This is to stop new users from bogging down the server and affecting existing connections. Check your configuration for values such as MaxClients, MaxSpareServers etc.

 

It depends. Are you on a shared server? Or do you have your own server? Is a dynamic content site with database? Or just html one?

 

its hosted on shared server.. powweb is the hosting company.. the site is a wordpress blog.. simple !
