Go up one level in this thread


In my experience, making small optimizations to the indexing scheme
which save 1/48th here and 1/64 there result in the data being
less compressable to the point where no saving in disk space were
gained.  My indexing method results in an average 10% of the index
space being for illegal or redundant positions, but compresses
very well.  I guess our goals differ.

Since my tablebase collection has roughly 3/4 TB positions in it,
I have given up on storing the indices in RAM, except for the
tables with less than 5 pieces.  I just rely on the OS to cache
recently accessed sections of the indices.
