--- Comment #11 from Tim Allison <talli...@apache.org> ---
I'm wary of microbenchmarks (especially when I write them), and these results
could be misleading.  I did include a warmup phase at.

At the very least, they show memory consumption is awful with Java, much better
with Zaxxer and still better with roaring.

Zaxxer is the fastest, with roaring doing better than Java at 100k, which is
well above what we think we'd need.

roaring does look to be better supported/more recent/more active community;
zaxxer has an interface that is closer to BitSet and would be an easier drop in
place kind of thing.  I did get an "IllegalArgumentException" with zaxxer on
one run, which gives me pause...
