Is there any documentation on what the settings for "Nalimov usage" really mean? I guess for "Frequently" I'd need to have either a solid-state disk or enough RAM to keep all tablebases in cache (and no, I don't have 7.5GB RAM to spare for the five-men tablebases :-) ), but what's the difference between "Normally" and "Rarely"? If I could, say, spare a gigabyte of RAM for the cases when Rybka is analyzing end games, would Normally be the right thing, or should I leave it at the default of Rarely?

Good question and difficult to answer, but i´ll try. TBs give precise information, but may cost time, in which cpu is idle. So it depends on both the processor speed, number of cores and speed of harddisk. Frequently might be good, if you got a slow cpu - eg. a Pentium I 100 MHz and a relatively fast harddisk. On computers with say a Core 2 Duo or quad and a normal 7200 rpm harddisk, "rarely" seems to be best. On my oct i use "normally", but tablebases are on a solid state disk with 0.2 ms access time. Before i got that ssd, i used a 15000 rpm SCSI disk - with that disk, "rarely" was best.
