Benchmarks MySQL: DDR400 vs DDR333
Does faster memory make a difference for the Opteron?| conc lev | Dual Opteron 848 DDR333 | Dual Opteron 848 DDR400 | Speedup DDR400 vs DDR333 |
| 1 | 174 | 190 | 9% |
| 2 | 279 | 287 | 3% |
| 5 | 353 | 337 | -5% |
| 10 | 351 | 353 | 1% |
| 20 | 371 | 377 | 2% |
| 35 | 370 | 375 | 1% |
| 50 | 372 | 373 | 0% |
No, that doesn't seem to be the case. All results point to a meagre 0 to 2% performance gain.

Would love to see how MS SQL performs in similar tests.mrVW - Thursday, December 2, 2004 - link
This test seems foolish to me. A 1GB database? All of that fits in ram.A database server is all about being the most reliable form of STORAGE, not some worthless repeat queries that you should cache anyway.
Transactions, logging... I mean how realistic is it to have a 1GB of database on a system with 4GB of RAM and expensive DB2 software.
A real e-commerce site likeMWave, NewEgg, Crucial could have 20GB per year! Names, addresses, order detail, customer support history, etc.
Once you get over a certain size, a database is all about disk (putting logging on one disk indepdent of the daata, etc.). The indexes do the main searching work.
This whole test seems geared to be CPU focused, but only a hardware hacker would apply software in such a crazy way.

man i would love to have one of those systems. Great job on the review you guys, its good to know that there are places where you can still get great independent analysis.Zac42 - Thursday, December 2, 2004 - link
