Thanks for your Quick & Valuable Response, 1. ANS-Question 1: No Both Are different Machine, We are using VirtualHost configuration 2. ANS-Question 2: Kindly please share Optimal Value to Set for ConnectionTimeout & KeepAliveTimeout if required 3. ANS-Question 3: Yes We have Firewall, but there is no rules. I just googled and updated this value to tuning server. Now I removed 4. ANS-Question 4: I am new to Apache, While searching in Google, Based on some recommandationI tried. I removed all these items.
Now I am monitoring systems, whether still its closing connections or not. sir, While directly using Tomcat URL, pages are loading 1-2 Seconds, but the same page taking 6-7 Seconds in WebServer URL. Also, If I didn't use WebServer URL for 30minutes and hit any URL, first time its taking more than 30 Seconds to load a page. Is there any option to tuning the system.
