FYI... I was curious to confirm that PulsingCodec (in trunk, with flexible indexing) gives good performance gains specifically for primary key fields... so I ran some performance tests and wrote up the results:
http://chbits.blogspot.com/2010/06/lucenes-pulsingcodec-on-primary-key.html Net/net PulsingCodec shows ~45-50% speedup on uncached (in OS's IO cache) lookups, and ~15% speedup on cached lookups...
