I did a little reading in my Hiarcs "read me files" and here is what it says:
Cache size (MB): The amount of memory used for caching tablebases. Access from
the cache is much faster than from disk. If you increase this value, more
information can be cached. But this is rarely useful for accessing the
tablebases since the access normally is pretty local, i.e. not so many different
endgames will occur in a short time.(It gives an example of 8192kb- for cache
size) This memory may be better used somewhere else. Building the tablebases is
different, a little bit more memory may be useful here. It don't give any
example to what you should use here, but it does say a liitle bit more can be
useful and so i would think about 16 Mb to 32 Mb would be plenty!
Memory size (MB): This is the amount of main memory needed to build the biggest
of the selected tablebases. This value may go up to 571MB. You can see
immediately if your machine is suitable to build the selected tablebases.
