I think Doron is right on the money here. I know one "customer" who'd be happy to trade its file descriptors for less IO - simpy.com. It's exactly what Doron describes - a busy system with a LOT of indices. File descriptors are kept under control by carefully closing IndexSearchers, plus I can always increase the max open-files limit. What I can't easily increase is the disk IO. Sure, I could go from CFS to the multi-file format, but it would be nice to have that third, middle ground choice.
Out of curiosity, does the non-compound format yield any search-time benefits? I would think that would be the case only if the system- level file stream feeding the the buffered IndexInput objects were maintaining its own (unnecessary) buffers.
