VM Guest LAN: QDIO Simulation
z/VM 4.3.0 now supports the ability to create a simulated QDIO adapter (as was done for HiperSockets in z/VM 4.2.0) using Guest LAN function provided by CP.
This section presents and discusses measurement results that assess the performance of Guest LAN QDIO support by comparing it to real OSA GbE adapters (QDIO), Guest LAN HiperSockets, and real HiperSockets.
Methodology: The workload driver is an internal tool which can be used to simulate such bulk-data transfers as FTP or primitive benchmarks such as streaming or request-response. The data are driven from the application layer of the TCP/IP protocol stack, thus causing the entire networking infrastructure, including the adapter and the TCP/IP protocol code, to be measured. It moves data between client-side memory and server-side memory, eliminating all outside bottlenecks such as DASD or tape.
A client-server pair was used in which the client sent one byte and received 20MB of data (streaming workload); or the client connected to the server, sending 64 bytes to the server, the server responded with 8K and the client then disconnected (connect-request-response workload); or in which the client sent 200 bytes and received 1000 bytes (request-response workload). Additional client-server pairs were added to determine if throughput would vary with an increase of number of connections.
At least 3 measurement trials were taken for each case, and a representative trial was chosen to show in the results. A complete set of runs was done with the maximum transmission unit (MTU) set to 1500 and 8992 for QDIO and Guest LAN QDIO, and 8K and 56K for HiperSockets and Guest LAN HiperSockets.
The measurements were done one a 2064-109 in an LPAR with 2 dedicated processors. The LPAR had 1GB central storage and 2GB expanded storage. CP monitor data was captured during the measurement run and reduced using VMPRF. APAR VM63091, which is on the 4301 Stacked RSU, was applied to pick up performance improvements made for Guest LAN QDIO support.
 |
Results: MB/sec (megabytes per second) or trans/sec (transactions per second) and response time were supplied by the workload driver. All other values are from CP monitor data or derived from CP monitor data.
Total_cpu_util | This field was obtained from the SYSTEM_SUMMARY_BY_TIME VMPRF report. It shows the average of both processors out of 100%. |
tcpip_tot_cpu_util | This field is calculated from the USER_RESOURCE_UTILIZATION VMPRF report (CPU seconds, total) for the tcpip1 and tcpip2. 100% is the equivalent of one fully utilized processor. |
cpu_msec/MB | This field was calculated from the previous tot_cpu_util divided by the number of megabytes per second to show the number of milliseconds of CPU time per megabyte. |
cpu_msec/trans | This field was calculated from the previous tot_cpu_util divided by the number of transactions per second to show the number of milliseconds of CPU time per transaction. |
The following tables compare Guest LAN QDIO with QDIO, Guest LAN HiperSockets and real HiperSockets for the streaming, CRR, and RR workloads with 10 clients.
Specific details are mentioned for each workload after the tables for
that workload.

With MTU size of 1500 QDIO did slightly better than Guest LAN
QDIO in both throughput and efficiency (CPU_msec/MB).
With MTU size of 8K or 8992,
Guest LAN QDIO is similar to Guest HiperSockets,
QDIO and real HiperSockets.

Again, with MTU size of 1500, QDIO did slightly better than Guest
LAN QDIO. However with similar size MTU (8K or 8992), Guest LAN
QDIO is more efficient, and gets slightly better throughput, than
the other three cases. This is an example of simulation of a device
not costing more than the real device.

Results for an MTU size of 1500 were similar to the previous two workloads. Results for similar MTU (8K or 8992) show Guest LAN QDIO performance that is similar to the other three cases.
The complete results are summarized in the following tables (showing all workloads and all client-server pairs).
A few runs (not shown) were done on a 2064-109 in
an LPAR with 3 dedicated processors
to see what effect another engine would have. The tests were
done with QDIO and real HiperSockets and showed a dramatic improvement
in throughput with 1, 5 and 10 clients and matching throughput for
20 clients. The CPU_msec/MB results were approximately the same
as for the 2-processor runs. This confirmed our suspicion that,
with 2 processors, there were times when one or more of the participating
virtual machines were waiting on
CPU, even though the averages did not show we were using all the CPU
cycles.
