AnalogX NetStat Live (NSL) is a small, easy to use TCP/IP protocol monitor which monitors the exact throughput on both incoming and outgoing data - whether using a modem, cable modem, DSL, or local network. NSL enables the user to see how quickly data goes from one computer to another on the internet. NSL will tell you how many other computers data must go through to get there (traceroute). NSL graphs CPU usage of the user's system in order to determine if it's the user's computer or the internet that's slowing things down.
