Doron Cohen commented on LUCENE-3262:
-------------------------------------
bq. I reduced those to 1-20 per document with depth of 1-3 and got results I
could live with.
I agree, tried this too now and the comparison is more reasonable.
Perhaps what are reasonable numbers (for #facets/doc and their depth) is
debatable, but I agree that 200 facets per document is too many.
Changing the defaults to 20/3 and preparing to commit.

> A spin off from LUCENE-3079. We should define few benchmarks for faceting
> scenarios, so we can evaluate the new faceting module as well as any
> improvement we'd like to consider in the future (such as cutting over to
> docvalues, implement FST-based caches etc.).
> Toke attached a preliminary test case to LUCENE-3079, so I'll attach it here
> as a starting point.
> We've also done some preliminary job for extending Benchmark for faceting, so
> I'll attach it here as well.
> We should perhaps create a Wiki page where we clearly describe the benchmark
> scenarios, then include results of 'default settings' and 'optimized
> settings', or something like that.
