Does disabling Windows firewall improve performance?
Disabling a firewall can boost performance, but doing so puts the entire network at risk. Companies that need a faster connection should either upgrade their equipment or their broadband service instead; the cost of recovering from a security breach can be far more expensive than the cost of new modem or router.

Does the order of firewall rules matter?
Firewall rules have a priority order that determines the order in which the rules are applied to network traffic. Therefore, the last rule of a firewall profile is the Deny rest rule. It blocks all the traffic that the rules above it do not specifically allow.
