t all small indexes together into a few files, and put each big index into its own file. At least for not too big databases, performance does not seem to depend very much on the block size. A value of 3 (block size 512 bytes) or 4 (1024) seems a good compromise. Only for very large databases (more than 10 million objects) I found that using very large blocks (6, resulting in 4096 bytes) improves performance. So much for now.
