Not quite true. Latency is also lower on a gigabit network; it doesn't send more packets in parallel, it sends packets faster, in serial. At any given speed, it takes time for some number of bytes to traverse the wire.
Though the minimum on-wire latency at 100MBit is 0.12ms for 1500-byte packets, per packet, typically 1GBit cards also have lower latency internally.
(You can multiply that 0.12ms number by the number of intervening switches, plus one.)
- ekianjo 11y agoInteresting, I was not aware of that. Do you have data as to how much latency there is on 1Gbit cards then ? Is it significantly lower?
