Please refer to my thread "excessive DNS slows httpd" in which I discuss a very slow response from my httpd server on my CentOS box after modifying httpd.config . I have "solved" the problem by blocking all DNS in iptables on my CentOS box. As it happens, this is not a problem in my present configuration, but it can hardly be considered a good solution. Given that the httpd configurations are essentially identical, it appears that there is a difference between my Feodora box and my CentOS box regarding how and when DNS is handled, at least when originated by httpd. Suggestions would be most welcome. Mike.

That is surely something in your configuration or a web application. It's not a general problem of Apache on CentOS, mine are all not doing that.
