Hannes,
I read your statement but I disagree about them being useless. Benchmarks
are relevant when comparing different DBs for performance; whether you use
your own benchmark tool and/or the vendors.
Your website says:
"How fast is it then?
As soon as we ship NexusDB we will provide a trial version. It is well
understood that benchmarks can only give an indication of how well the
engine performs and that every benchmark is biased to a certain engine. We
are very confident that you will see similar improvements to those that we
found in our internal tests, by simply trying your app with the trial
version. We are confident that NexusDB out-performs the competition - try it
and see for yourself!"
The statement "It is well understood that benchmarks can only give an
indication of how well the engine performs and that every benchmark is
biased to a certain engine" does not totally hold up. Sure, some vendors
may or willfully skew the results to benefit them. Again, you have to do the
benchmark yourself. DB performance is generally always an issue that must be
dealt with.

Good for you and glad to hear it. Good luck!
