I wish they wouldn't do this, it seems that they simply do not want to talk about this topic, even though the reason people usually choose Datomic is not performance but rather its abstractions -- so why the hostile attitude?
I think they've said before that they don't want someone saying the performance sucks when it is really just a bad query or something else that isn't the databases fault...this is usually the reason why talking about performance is outlawed.
But an analogous situation holds for almost all performance benchmarks of any product right? That seems to be an argument against ever making any benchmarks public.
I wonder if there are many respectable companies that don't allow you to post benchmarks. It's almost as if they don't have any confidence in their product that they have to resort to such extraordinary measures.
Oracle, Microsoft. They're called "DeWitt clauses", after the researcher who first invoked Oracle's wrath after publishing benchmarks and finding them to be the slowest. Read on:

There are a few more (but not many functionst) that are a compromise, so I expect that Haskellers would have a few objections. But, this is Clojure, and not haskell :)
