> I have hacked together a FixedIntBlockIndex impl with Group VarInt encoding - this does way worse than standard codec in benchmarks but I guess that is mainly due to the FixedIntBlockIndex limitations. Once LUCENE-2723 is in / or builds with trunk again I will update and run some tests. The isolated microbenchmark shows that there could be improvements over vint even in java though and I am sure we can make it faster impl. wise.
