Please use Keep Alive as it will increase the performance of your server. Disable keep Alive settings only when there is a firewall in between web or app. Or you are facing package drop issues/connection reset msg.

• You can increase your users to any numbers as explained above by increase max client and server limits of your systems.
• Always define min-maxspare or min-maxthread limits.
• One very important point if you are unable to increase the max client limit , just increase the listen backlog limit it will take the extra requests in the queue which in turn prevents the connection drop.
