AMD Opteron vs. Intel Xeon: Database Performance Shootout

To give you an idea of the scale of this benchmark we have graphs of stored procedures calls per second. We decided to focus on Stored Procedures / Second rather than Transactions / Second as the definition of a Transaction can have a business context or a technical context.
An interesting preview of the results to come: in 2-way configurations the Xeon is actually able to slightly outperform the Opteron. The added cache and 3.0GHz+ clock speed does seem to help the Xeon tremendously.
The Opteron goes from lagging slightly behind the Xeon to offering a 8.5% performance advantage in a 4-way configuration. The Xeon's shared FSB severely clips its wings when moving to a 4-way setup.
If you're familiar with these sort of database applications, the above graphs will give you a good idea of what sort of stress we're putting on these systems; we are pushing enterprise class performance limits. Now onto the results:

Hmm... the site below has some info about Numa (non unified memory architecture), and it looks like the os you're using isn't Numa enabled... Is this correct? Is there any real world benefit from Numa with Opteron?http://www.gamepc.com/labs/view_content.asp?id=opt...

Could you speculate which way the advantage should be going in a BI benchmark (say TPC-H type of a test)? These are long running queries with gigabytes size tables.Jason Clark - Wednesday, March 3, 2004 - link
We started playing around with a couple of mysql benchmarks a few weeks ago namely OSDB and some new multithreaded benchmarks from MySQL themselves. We're hoping to get some valid tests that produce real results in the future.Cheers.

In fact we did some recent testing to start out 64bit linux testing and mysql 4.0.17 on suse 64 had a segmentation fault starting <WINK> known issue for mysql as well... <WINK> <WINK>Jason Clark - Wednesday, March 3, 2004 - link
Steveoc, it hardly runs like a dog. Let's not turn this into a one sided os war :) The test make sense as they are, but a 64bit article is on the books for later. We've already been playing around with Suse 64bit and some others and whether you agree or not 64bit is still immature, period full stop. Support is there but it has some maturing to do.steveoc - Wednesday, March 3, 2004 - link
All these tests show is that Opteron, running Windows, runs like a Dog. As if we couldnt predict that result already ...The tests will only make sense once you are running 64bit linux. In fact, Id love to see a test of Dual Xeon + Win2003 + MSSQL vs Dual Opteron + 64bit Gentoo + 64bit MySQL .. that would be very interesting indeed.
For anyone out there claiming that '64bit software has a looong way to go', that is only true for Windows. Unix (and Linux) have been running 64bit for a long time now, and the AMD64 has very good support under Linux.

Seeing the difference whether NUMA us used or not would be *VERY* interesting. Also comparing against other NUMA aware OS's (Linux 2.63 or better kernel, or whatever) would be a good test too.hirschma - Wednesday, March 3, 2004 - link
#25 - Seems that it is not for sale to the general public, not that I could find. If anyone knows where/how to get one, please let me know.I have an application that is quite expensive and is licensed by the box, no matter how many CPUs it has ;) I'm guessing that building a low-end quad would give me more throughput per $$ than a second license/second box.

We're also looking at some 64bit .NET benchmarks as we're real close to having a real-world application that we can hammer.Jason Clark - Wednesday, March 3, 2004 - link
An interesting article would be the effect of NUMA on enterprise level applications. GamePC did a bit of a write up on it, but it was limited to desktop and synthetic benchmarks. Would any of you be interested in seeing the effects of NUMA on and off on the sql tests?
