Benchmarks MySQL: Single versus Dual
Let us check how MySQL scales from one Xeon to a second one. As always, Hyperthreading is enabled on both CPUs.| conc lev | Single Xeon 3.06 1 MB L3 | Dual Xeon 3.06 1 MB L3 | Dual Speedup |
| 1 | 102 | 110 | 8% |
| 2 | 137 | 175 | 28% |
| 5 | 153 | 206 | 34% |
| 10 | 158 | 218 | 38% |
| 20 | 162 | 218 | 35% |
| 35 | 160 | 233 | 45% |
| 50 | 157 | 222 | 42% |
MySQL doesn't seem to scale as well as DB2. We measured a 40% performance increase when the concurrency level is high enough. Might this be an important difference between the big established players and the Open Source database?

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
