One thing I found that will help is increasing your EGTB cache to 256mb. It
helps a LOT with the 3-4-5 piece EGTBs. With 16mb cache Shredder 9 was going
~200kn/s (much hard drive accessing). I increased it to 256mb and started
analyzing the position again. After the few seconds of loading EGTBs into memory
initially the hard drive was quiet and the NPS shot up to ~1.1 million. During a
game it will slowly load the EGTBs into the large cache as it moves towards the
endgame (keeping NPS high) instead of doing it all at once when starting to
analyze a fresh endgame position. Helped me quite a bit.
