Database test: AMD Socket F

In our previous review we presented test results that were gathered with PostgreSQL as a database for the first time. Since its performance and scalability positively suprised us, we'll definately keep using it in future reviews. Like before, it didn't turn us down this time. While the performance of MySQL clearly went downhill after the switch to DDR2, PostgreSQL was able to hold on to it. On average, only 1 percent of its performance was lost after the transition. This would even mean a small victory for the DDR2 Opteron if the same amount of memory had been used.


When we compare the performance of MySQL and PostgreSQL on the platform of two dual core Socket F processors, an apparent pattern emerges regarding the strengths and weaknesses of the two packages. MySQL outperforms PostgreSQL when under a load of up to ten simultaneous users. Above that number, the curve bends and performance starts to decrease again. In contrast, PostgreSQL holds on comfortably to its performance peak, even at a concurrency of 100.
