We generally avoid posting benchmarks and suggest people create their own targeting their use cases. However, we have decided to publish a few of our internal micro-benchmarks comparing 1.2 with 1.4RC2 (aka 1.3.5) to show that in almost all cases performance is the same or better (sometime significantly so), even though we’ve added many new features.
The test works by spawning N threads and having them hammer the DB with one operation as fast as they can. It is probably best to ignore the raw numbers and only look at the relative performance. In particular, these numbers shouldn’t be compared against other databases.
A few highlights (and one lowlight):
This test was run on an Intel Core i7 Quad 860 2.8GHz with 8GB of RAM and an Intel G2 SSD. Even though they improved performance, HyperThreading and TurboBoost were disabled as they can skew results in nondeterministic ways.
