Data Warehouse Test Explained
We are always looking to improve the quality of our reviews and as a result, we have added a new Stress Test to our suite.
This "Data Warehouse" test is focused on large record sets with plenty of aggregation. This test is based on a system that we developed to track and manage Request statistics for www.AnandTech.com and Forums.AnandTech.com. It tracks statistics like Requests/Hour, Requests/Hour/IP Address, Unique IP Addresses/Hour, Unique Users/Hour, Daily Browser stats, etc. These stats are further summarized by site, i.e.: www or Forums.
As with the other Stress Tests, each test was repeated three times and the average between the three tests was used. For this Data Warehouse Stress Test, we defined a quantity of work to complete and measured how long each platform required to process the workload.
So, to ensure that IO was not the bottleneck, each test was started with a database, including tempdb, which had already been expanded so that autogrow activity did not occur during the test. During the execution of the tests, there were no applications running on the server or monitoring software. Task Manager, Profiler, and Performance Monitor where used when establishing the baseline for the test, but never during execution of the tests.
At the beginning of each platform, the server was rebooted to ensure a clean and consistent environment. The database was always copied to the 8 disk RAID 0 array with no other files present to ensure that file placement and fragmentation was consistent between runs. In between each of the three tests, the database was deleted, the original database was copied again to the array, and SQL Server was restarted.
There is no "client" required for this test. The workload is initiated by a stored procedure call from Query Analyzer.

is it possible to have a dual proc setup without using registered memory?Proton - Tuesday, February 15, 2005 - link
"We did a revamp of the tool itself, which is more performant on high volume queries."Performant?
Please read this article...

"More recently, we've seen the word "performant" start its crawl into the everyday vocabulary of devspace. It is used to mean "highly performing." It's also not a word. When something provides information, it's informative. It's not "informant." The word "performant," if it existed, would be a noun—not an adjective. But it doesn't exist, so if you do see it in print, remember that it's not really there.'

#15 Jason, let me rephrase that#10: "However compact"... That would do it more justice ;-)I didn't thank you for the effort you and Ross put into this, did I? Your article came out together with the announcements of AMD. Hot stuff! How much time/sleep did you really have?

"What memory timings?"Good question...
"is it dual vs Dual or single vs single"
single vs single, 32bit

Wait... I think I miss something here.. is it dual vs Dual or single vs single?Zebo - Tuesday, February 15, 2005 - link

"I don't know if it fixes the IOMMU issue or not"As far as we know, it doesn't. The Smithfield is a desktop part, so that is to be expected...large quantities of memory aren't yet necessary for the desktop.
"Now this is interesting. Somewhere were Intel comes out on top by a big margin"
(grin) Only the most diehard AMD fan would deny Xeon's capabilities...
For a 1 or 2 CPU server that is used for low-end database serving or webserving, the new Xeon is excellent in 32bit (the CPU of choice)!
As the next few months grind ahead, we will see quite a few scenarios on review sites. My own suppositions are that
1. In a 1 or 2 single core Opteron system there is almost no bandwidth constraint. This is evidenced by the lack of change with the 25% HT increase to 1GHz. That said, we might see significant changes in 4 and 8 way systems, especially as dual cores come on-line.
2. We still have no reviews of these two platforms in 64bit using >4GB of ram. I suspect that Opteron will be much more effective there...
3. When Intel releases their mp Xeon Nocona, I suspect that 4 and 8 way Opteron systems will blow their doors off...my rationale is that the 1GHz HT links and AMD's MOESI cache protocol gives them a huge advantage in scaling processors.

BTW... there is a new chipset (or some new chipsets) being released soon along with the Smithdale CPU. I don't know if it fixes the IOMMU issue or not, but it might be worth a look...Viditor - Monday, February 14, 2005 - link
"no mention in any of the access scenarios is described as 32bit..."Oops...yes it does.
"Some devices, such as a large majority of PCI cards cannot directly access memory above the 4GB point"
