-Overview of test results
-------------------------
-
-See Grafana_ for viewing test result metrics for each respective test case. It
-is possible to chose which specific scenarios to look at, and then to zoom in
-on the details of each run test scenario as well.
-
-All of the test case results below are based on 4 scenario test runs, each run
-on the LF POD2_ or Ericsson POD2_ between September 16 and 20 in 2016.
-
-TC002
------
-The round-trip-time (RTT) between 2 VMs on different blades is measured using
-ping. Most test run measurements result on average between 0.32 ms and 1.42 ms.
-Only one test run on Sep. 20 has reached greatest RTT spike of 4.66 ms.
-Meanwhile, the smallest network latency is 0.16 ms, which is obtained on Sep.
-17th. To sum up, the curve of network latency has very small wave, which is
-less than 5 ms. SLA sets to be 10 ms. The SLA value is used as a reference, it
-has not been defined by OPNFV.
-
-TC005
------
-The IO read bandwidth actually refers to the storage throughput, which is
-measured by fio and the greatest IO read bandwidth of the four runs is 734
-MB/s. The IO read bandwidth of the first three runs looks similar, with an
-average of less than 100 KB/s, except one on Sep. 20, whose maximum storage
-throughput can reach 734 MB/s. The SLA of read bandwidth sets to be 400 MB/s,
-which is used as a reference, and it has not been defined by OPNFV.
-
-The results of storage IOPS for the four runs look similar with each other. The
-IO read times per second of the four test runs have an average value between
-1.8k per second and 3.27k per second, and meanwhile, the minimum result is
-only 60 times per second.
-
-TC010
------
-The tool we use to measure memory read latency is lmbench, which is a series of
-micro benchmarks intended to measure basic operating system and hardware system
-metrics. The memory read latency of the four runs is between 1.085 ns and 1.218
-ns on average. The variations within each test run are quite small. For
-Ericsson pod2, the average of memory latency is approx. 1.217 ms. While for LF
-pod2, the average value is about 1.085 ms. It can be seen that the performance
-of LF is better than Ericsson's. The SLA sets to be 30 ns. The SLA value is
-used as a reference, it has not been defined by OPNFV.
-
-TC012
------
-Lmbench is also used to measure the memory read and write bandwidth, in which
-we use bw_mem to obtain the results. The four test runs all have a narrow range
-of change with the average memory and write BW of 18.5 GB/s. Here SLA set to be
-15 GB/s. The SLA value is used as a reference, it has not been defined by OPNFV.
-
-TC014
------
-The Unixbench is used to evaluate the IaaS processing speed with regards to
-score of single cpu running and parallel running. It can be seen from the
-dashboard that the processing test results vary from scores 3209k to 3843k, and
-there is only one result one date. No SLA set.
-
-TC037
------
-The amount of packets per second (PPS) and round trip times (RTT) between 2 VMs
-on different blades are measured when increasing the amount of UDP flows sent
-between the VMs using pktgen as packet generator tool.
-
-Round trip times and packet throughput between VMs can typically be affected by
-the amount of flows set up and result in higher RTT and less PPS throughput.
-
-The mean packet throughput of the three test runs is between 439 kpps and
-582 kpps, and the test run on Sep. 17th has the lowest average value of 371
-kpps. The RTT results of all the test runs keep flat at approx. 10 ms. It is
-obvious that the PPS results are not as consistent as the RTT results.
-
-The No. flows of the four test runs are 240 k on average and the PPS results
-look a little waved, since the largest packet throughput is 680 kpps and the
-minimum throughput is 319 kpps respectively.
-
-There are no errors of packets received in the four runs, but there are still
-lost packets in all the test runs. The RTT values obtained by ping of the four
-runs have the similar trend of RTT with the average value of approx. 12 ms.
-
-CPU load is measured by mpstat, and CPU load of the four test runs seem a
-little similar, since the minimum value and the peak of CPU load is between 0
-percent and ten percent respectively. And the best result is obtained on Sep.
-17th, with an CPU load of ten percent. But on the whole, the CPU load is very
-poor, since the average value is quite small.
-
-TC069
------
-With the block size changing from 1 kb to 512 kb, the average memory write
-bandwidth tends to become larger first and then smaller within every run test
-for the two pods, which rangs from 25.1 GB/s to 29.4 GB/s and then to 19.2 GB/s
-on average. Since the test id is one, it is that only the INT memory write
-bandwidth is tested. On the whole, with the block size becoming larger, the
-memory write bandwidth tends to decrease. SLA sets to be 7 GB/s. The SLA value
-is used as a reference, it has not been defined by OPNFV.
-
-TC070
------
-The amount of packets per second (PPS) and round trip times (RTT) between 2 VMs
-on different blades are measured when increasing the amount of UDP flows sent
-between the VMs using pktgen as packet generator tool.
-
-Round trip times and packet throughput between VMs can typically be affected by
-the amount of flows set up and result in higher RTT and less PPS throughput.
-
-The network latency is measured by ping, and the results of the four test runs
-look similar with each other, and within these test runs, the maximum RTT can
-reach 27 ms and the average RTT is usually approx. 12 ms. The network latency
-tested on Sep. 27th has a peak latency of 27 ms. But on the whole, the average
-RTTs of the four runs keep flat.
-
-Memory utilization is measured by free, which can display amount of free and
-used memory in the system. The largest amount of used memory is 269 MiB for the
-four runs. In general, the four test runs have very large memory utilization,
-which can reach 251 MiB on average. On the other hand, for the mean free memory,
-the four test runs have the similar trend with that of the mean used memory.
-In general, the mean free memory change from 231 MiB to 248 MiB.
-
-Packet throughput and packet loss can be measured by pktgen, which is a tool
-in the network for generating traffic loads for network experiments. The mean
-packet throughput of the four test runs seem quite different, ranging from
-371 kpps to 582 kpps. The average number of flows in these tests is
-240000, and each run has a minimum number of flows of 2 and a maximum number
-of flows of 1.001 Mil. At the same time, the corresponding average packet
-throughput is between 319 kpps and 680 kpps. In summary, the PPS results
-seem consistent. Within each test run of the four runs, when number of flows
-becomes larger, the packet throughput seems not larger at the same time.
-
-TC071
------
-The amount of packets per second (PPS) and round trip times (RTT) between 2 VMs
-on different blades are measured when increasing the amount of UDP flows sent
-between the VMs using pktgen as packet generator tool.
-
-Round trip times and packet throughput between VMs can typically be affected by
-the amount of flows set up and result in higher RTT and less PPS throughput.
-
-The network latency is measured by ping, and the results of the four test runs
-look similar with each other. Within each test run, the maximum RTT is only 24
-ms and the average RTT is usually approx. 12 ms. On the whole, the average
-RTTs of the four runs keep stable and the network latency is relatively small.
-
-Cache utilization is measured by cachestat, which can display size of cache and
-buffer in the system. Cache utilization statistics are collected during UDP
-flows sent between the VMs using pktgen as packet generator tool. The largest
-cache size is 213 MiB, and the smallest cache size is 99 MiB, which is same for
-the four runs. On the whole, the average cache size of the four runs look the
-same and is between 184 MiB and 205 MiB. Meanwhile, the tread of the buffer
-size keep stable, since they have a minimum value of 7 MiB and a maximum value of
-8 MiB.
-
-Packet throughput can be measured by pktgen, which is a tool in the network for
-generating traffic loads for network experiments. The mean packet throughput of
-the four test runs differ from 371 kpps to 582 kpps. The average number of
-flows in these tests is 240k, and each run has a minimum number of flows of 2
-and a maximum number of flows of 1.001 Mil. At the same time, the corresponding
-packet throughput differ between 319 kpps to 680 kpps. Within each test run
-of the four runs, when number of flows becomes larger, the packet throughput
-seems not larger in the meantime.
-
-TC072
------
-The amount of packets per second (PPS) and round trip times (RTT) between 2 VMs
-on different blades are measured when increasing the amount of UDP flows sent
-between the VMs using pktgen as packet generator tool.
-
-Round trip times and packet throughput between VMs can typically be affected by
-the amount of flows set up and result in higher RTT and less PPS throughput.
-
-The RTT results are similar throughout the different test dates and runs
-between 0 ms and 24 ms with an average leatency of less than 13 ms. The PPS
-results are not as consistent as the RTT results, for the mean packet
-throughput of the four runs differ from 370 kpps to 582 kpps.
-
-Network utilization is measured by sar, that is system activity reporter, which
-can display the average statistics for the time since the system was started.
-Network utilization statistics are collected during UDP flows sent between the
-VMs using pktgen as packet generator tool. The largest total number of packets
-transmitted per second look similar for the four test runs, whose values change a
-lot from 10 pps to 697 kpps. However, the total number of packets received per
-second of three runs look similar, which have a large wide range of 2 pps to
-1.497 Mpps, while the results on Sep. 18th and 20th have very small maximum
-number of packets received per second of 817 kpps.
-
-In some test runs when running with less than approx. 251000 flows the PPS
-throughput is normally flatter compared to when running with more flows, after
-which the PPS throughput decreases. For the other test runs there is however no
-significant change to the PPS throughput when the number of flows are
-increased. In some test runs the PPS is also greater with 251000 flows
-compared to other test runs where the PPS result is less with only 2 flows.
-
-There are lost packets reported in most of the test runs. There is no observed
-correlation between the amount of flows and the amount of lost packets.
-The lost amount of packets normally differs a lot per test run.
