On the other hand, if you are using SSD or something yielding 100 Gigabytes per second per direction data rate and system bus capable of handling that with other activities on the computer, then it will be fast. Localhost off a USB 2.0 Hard drive will yield maybe 480 Mbps or less because of the bus of the local hard drive that you are using to run the local webserver via localhost.
Localhost 'local loopback' runs as fast as your CPU, RAM, and chipset (SATA, IDE, etc.), and other local physical limits of the computer. local port 32840 connected with port 5001 The local ip fast, because it doesn't use physical device and 2-layers.( It never hits your NIC) iperf -c 1111 -t 5Ĭlient connecting to 109.191.109.241, TCP port 5001
127.0.0.1 is no faster any other local ip.
