MapDB benchmarks

Jan Kotek

Most of you probably know MapDB. It is alternative java collection

I ran some benchmarks on recent version. It compares ConcurrentHashMap and
ConcurrentSkipListMap with HTreeMap and BTreeMap from MapDB. I would like to
know your opinion. My collections are only 10x slower in some cases :-)



I posted other benchmarks about a year ago, those were broken because of
java.util.Random overhead. I think similar problem is not here.

Current bench is single-threaded. I have some problems with lock overlaps etc,
but it is under control. Final MapDB 2.0 should be linearly scalable to 4 cpu
cores, I will add tests once its done.
