Subject: Re: [PATCH RFC 0/4] xfs: Transmit flow steering
Here is a quick look at performance tests for the result of trying the
prototype fix for the packet reordering problem with VMs sending over
an XPS-configured NIC. In particular, the Emulex/Avago/Broadcom
Skyhawk. The fix was applied to a 4.4 kernel.
Before: 3884 Mbit/s
After: 8897 Mbit/s
That was from a VM on a node with a Skyhawk and 2 E5-2640 processors
to baremetal E5-2640 with a BE3. Physical MTU was 1500, the VM's
vNIC's MTU was 1400. Systems were HPE ProLiants in OS Control Mode
for power management, with the "performance" frequency governor
loaded. An OpenStack Mitaka setup with Distributed Virtual Router.
We had some other NIC types in the setup as well. XPS was also
enabled on the ConnectX3-Pro. It was not enabled on the 82599ES (a
function of the kernel being used, which had it disabled from the
first reports of XPS negatively affecting VM traffic at the beginning
of the year)
Average Mbit/s From NIC type To Bare Metal BE3:
NIC Type,
CPU on VM Host Before After
------------------------------------------------
ConnectX-3 Pro,E5-2670v3 9224 9271
BE3, E5-2640 9016 9022
82599, E5-2640 9192 9003
BCM57840, E5-2640 9213 9153
Skyhawk, E5-2640 3884 8897
For completeness:
Average Mbit/s To NIC type from Bare Metal BE3:
NIC Type,
CPU on VM Host Before After
------------------------------------------------
ConnectX-3 Pro,E5-2670v3 9322 9144
BE3, E5-2640 9074 9017
82599, E5-2640 8670 8564
BCM57840, E5-2640 2468 * 7979
Skyhawk, E5-2640 8897 9269
* This is the Busted bnx2x NIC FW GRO implementation issue. It was
not visible in the "After" because the system was setup to disable
the NIC FW GRO by the time it booted on the fix kernel.
Average Transactions/s Between NIC type and Bare Metal BE3:
NIC Type,
CPU on VM Host Before After
------------------------------------------------
ConnectX-3 Pro,E5-2670v3 12421 12612
BE3, E5-2640 8178 8484
82599, E5-2640 8499 8549
BCM57840, E5-2640 8544 8560
Skyhawk, E5-2640 8537 8701
happy benchmarking,
