Work out frames per second (network) instantly with clear inputs, formula shown and shareable results.
Frame rate at line rate is link bits divided by bits per frame including the 20-byte preamble and inter-frame gap. Ten gigabit Ethernet with minimum 64-byte frames reaches about 14.88 million frames per second, which is the standard benchmark figure and the number that determines whether a forwarding engine can handle worst-case traffic.
Frame rate
bits per frame = (frame bytes + 20) x 8; frames per second = link bits / bits per frame
It is the maximum frame rate of 10 Gigabit Ethernet with 64-byte frames, and it defines the worst-case packet processing requirement for any 10G device.
Dramatically. A 9000-byte frame at 10 Gbps is only about 138,000 frames per second, which is why jumbo frames cut CPU load so much for bulk transfer.
