| OLTP: Oracle Charbench "Calling Circle" | |
| Operating System | Windows 2008 Enterprise RTM (64-bit) |
| Software | Oracle 10g Release 2 (10.2) for 64-bit Windows |
| Benchmark software | Swingbench/Charbench 2.2 |
| Database Size | 9 GB |
| Typical error margin | 2-2.5% |
In our last review, we included our first Oracle benchmark. In this review, we are happy to announce that we finally tamed the Oracle beast … somewhat. The first benchmark we tried (see our AMD Opteron 8384 2.7GHz review) was "Order Entry", but this benchmark is designed for Oracle Real Application Clusters and right now we could not make it scale above eight cores. Even the gains from four to eight cores were pretty small, despite many experiments (increasing the number of users and so on). With Calling Circle, we increased the database size to 9.5GB to make sure that once again locking contention was not completely killing off multi-core performance. To reduce the pressure on our humble storage system, we increased the SGA size (Oracle buffer in RAM) to 10GB and the PGA size was set at 1.6GB. A calling circle test consists of 83% selects, 7% inserts, and 10% updates.
The "calling circle" test runs for 10 minutes. The test is repeated six times and the results of the first run are discarded. The reason for discarding the first run is that the disk queue length is sometimes close to 1, while the second run and later have a DQL of 0.2 or lower. In this case it was rather easy to run the CPUs at 99% load. All configurations below are dual CPUs.
We have seen this picture before: the latest Opteron has no problem with leaving the older generations of Xeons behind. However, the newest Xeon is simply running circles around the rest of the pack. It is a mind blowing 95% faster than the Xeon 5472 and 85% than the Opteron 8384 2.7GHz. SMT is formidable weapon, as Oracle makes good use of the extra threads, and it provides a 35% performance increase.

We've a customer who is interested in upgrading to Nehalem. He's running on Windows with Oracle database for SAP Enterprise Portals.Could you kindly let us know your recommendations please?
The approximate concurrent users would be around 3000 Portal users.
Keenly looking forward for your response and if you could state any instances of Nehalem installed in SAP environment for production usage, that would be a great deal of help.
Regards,
Chary

Hello,I understand the PHP not-enough-threads explanation as to why Dual X5570 doesn't scale up.
But, can anyone please explain why when you add another AMD Opteron 2384 the increase is from 42.9 to 63.9, while when you add another Xeon X5570 there isn't such an increase?
Thank you for the article,
Adun.

Was it really too much effort to clean off the processor before posting a picture of it? Or were they trying to show that it was used, tested?LizVD - Friday, April 3, 2009 - link
Would you perhaps like us to draw a smiley face on it as well? ;-)GazzaF - Wednesday, April 1, 2009 - link
Well done on an excellent review using as many real-world tests as possible. The VMWare test is a real eye opener and shows how the 55xx can match double the number of CPUs from the last generation of Xeons *AND* crucially save $$$$ on licensing from Windows and MS SQL and other per-socket licensed software, plus the power saving which is again a financial saving if you hire rack space in a datacentre.I eagerly await your own in-house VM tests. Please consider also testing using Windows 2008 Hyper-V which I think doesn't have the 55xx optimisations that the latest release of VMWare has (and might not have until R2?).
Thanks for the time you put in to running the endless tests. The results make a brilliant business case for anyone wanting to upgrade their servers. You must have had the chips a good week before Intel officially launched them. :-) I do feel sorry for AMD though. I'm sure they have plenty of motivation to come back with a vengeance like they did a few years ago.

Thanks! Good to hear from another professional. I believe the current Hyper Beta R2 already has some form of support for EPT.Our virtualization testing is well under way. I'll give an update soon on our blog page.

You mention octal servers from Sun and HP for VM's, but does anybody really use these systems for VM's? I can't imagine why anybody would, since you are paying a serious premium for 8 sockets vs. 2 x 4 socket servers, or even 4 x 2 socket servers. Then the redundancy options are much lower when running only a few 8 socket servers vs many 2 or 4 socket servers when utilizing v-motion, and the expansion options are obviously far less w/ NIC's and HBA's. From what I've seen, most 8 socket systems are for DB's.Veteran - Wednesday, April 1, 2009 - link
What i mentioned after reading the review is there are very few benches on benchmarks a little bit favored by AMD.For example, only 1 3DSmax test (so unusefull) at least 2 are needed
Only 1 virtualization benchmark, which is really a shame....
Virtualization is becoming so important and you guys only throw in one test?
Besides that, the review feels a bit biased towards intel, but i will check some other reviews of the xeon 5570

Virtualization benchmark come from the official Vmmark scores.However there is something real strange going on in the results...
HP HP ProLiant DL370 G6
VMware ESX Build #148783 VMmark v1.1
23.96@16tiles
View Disclosure 2 sockets
8 total cores
16 total threads 03/30/09
Dell Dell PowerEdge R710
VMware ESX Build #150817 VMmark v1.1
23.55@16tiles

VMware ESX Build #148592 VMmark v1.1

VMware ESX v3.5.0 Update 4 VMmark v1.1
14.22@10 tiles
View Disclosure 2 sockets
8 total cores
16 total threads 03/30/09
So lets see all the prebuilds of esx3.5 update 4 get a real high score of 16 tiles almost as much as a 4s shanghai while Vmware performance team themselves stated that we should never see the HT core as a real cpu in Vmware (even with the new code for HT) while yet the benchmark shows a high performance increase, no not like anandtech is stating that this is due to the more available memory and its bandwith, those Vmmarks are not memory starving. Now look at the official Intel benchmark with ESX update 4, it provides 10 tiles and a healthy increase, that from a technical point of view seems much more realistic. All other marketing stuff like switching time etc, all nice, but then again is within the same line of current shanghai.

What kind of tests are you looking for? The techreport guys have a lot of HPC tests, we are focusing on the business apps."very few benches on benchmarks a little bit favored by AMD."
That is a really weird statement. First of all, what is a test favored by AMD?
Secondly, this new kind of testing with OLTP/OLAP testing was introduced in the Shanghai review. And it really showed IMHO that there was a completely wrong perception about harpertown vs Shanghai. Because Shanghai won in the tests that mattered the most to the market. While many tests (inclusive those of Intels) were emphasizing purely CPU intensive stuff like Blackscholes, rendering and HPC tests. But that is a very small percentage of the market, and that created the impression that Intel was on average faster, but that was absolutely not the case.
"Only 1 virtualization benchmark, which is really a shame..."
Repeat that again in a few weeks :-). We have just succesfully concluded our testing on Nehalem.
Personally I am a bit shocked about the "not enough tests" :-). Because any professional knows how hard these OLTP/OLAP tests are to set up and how much time they take. But they might not appeal to the enthousiast, I am not sure.
