Hi, this is a pretty interesting class for is, in Directory. I have done a lot of benchmarks ths year, and what I get is that HashMap is heavily used, and GC represnets around 30 % of all CPU, when the server is really loaded, on a multi-CPU system.
So I guess that if we can have a fastest (maybe) but also a low memory footprint lib, we will have a real gain. It has to be checked, of course. btw, I checked the License, and it is compatible with ASL2. A good move, if the classes are ok, would be to push them in commons-collection.
