Vsperf Multi-Flow testing
Introduction
The purpose of this series of testing is to examine the impact of sending multiple streams thought the OVS bridge on the flow throughput and performance. Testing 2544 zero loss on both PVP and Phy2Phy2 modes.
Test Goals:
To document any disparity in flow processing between Layer 2,Layer 3 and Layer 4 for flows ranging between 1,000 through 1 million.
To determine any any significant limitations or anomalies in processing in the handling of flows based on ranges that would affect performance when deployed in specific situations. Or when using in qualifications labs.
To characterize the Multiflow performance for VSPERF that can be used to compare for future benchmarking.
Test Non-Goals:
This is not a maximum performance testing setup. The system has been tuned to provide it’s best performance to ensure consistent results for this test. These results should not be used as a set of limitations for the software as different hardware configurations will be able to give different results.
These results are are to be used to compare within this dataset to each other.
This testing does not reflect performance limitations of the traffic generator used in this case. Other tools will have different abilities. One generate was used for consistent results.
Test Configuration:
Figure 1: Test Setup
System Configuration
Isolated all NUMA 1 CPU’s using tuned cpu parameters.
DPDK_SOCKET_MEM = ['4096', '4096']
VSWITCH_VHOST_CPU_MAP = [5,7,13,15]
VSWITCH_PMD_CPU_MASK = 'a0a0'
GUEST_SMP = ['3']
GUEST_CORE_BINDING = [('1', '9', '11')]
GUEST_TESTPMD_PARAMS = ['-l 0,1,2 -n 1 --socket-mem 2048 -- '
'--burst=64 -i --txqflags=0xf00 '
'--disable-hw-vlan --nb-cores=2, --txq=1 --rxq=1 --rxd=1024 --txd=1024']
Data Sets:
Test Data was determined by using the max number of each of the 5 iterations. This was to rule out one aberrations in the zero loss test that causes lower numbers infrequalty but impacted a flow here and there. 5 iterations were used to determine we had a level of confidence in the test numbers reported.
