Does disabling firewall make Internet faster?
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.
