Latency Intel Pro/1000 on P4DP6
  • Motherboard SuperMicro P4DP6 Chipset Intel
    E7500 (Plumas)
  • CPU Dual Xeon Prestonia (2cpu/die) 2.2 GHz Slot
    4 PCI, 64 bit, 66 MHz
  • RedHat 7.2 Kernel 2.4.14
  • Latency high but smooth
  • Indicates Interrupt coalescence
  • Slope 0.0136 us/byte
  • Expect
  • PCI 0.00188
  • GigE 0.008

  • ITP4007
  • 1400 bytes sent
  • Wait 1000 us
  • Send CSR time 2.0 us
  • Send Data time 3.25 us
  • Recv Data time 2.2 us
  • Slot 3 to slot 5
  • ITP4001
  • Detail of 1400 bytes sent
  • CSR time 2.2 us
  • Data time 3.2 us
  • Slot 4 to slot 4
  • Small differences between slots
