title: Apache equivalent to IIS application pool
body: <p>I have an Apache server, and there are many sites in it. One or two of these sites are consuming the whole server's resources, consuming almost all the MPM processes, which leads to the server failing and all the other sites becoming very slow.</p>
  
  <p>Is it possible to implement something like an <a href="https://technet.microsoft.com/en-us/library/cc735247%28v=ws.10%29.aspx" rel="nofollow">application pool in IIS</a> in Apache server to avoid other sites becoming slow when one site is consuming all the server resources?</p>
