All tests executed on my notebook AMD (K6) 300 MHz, 256 MB RAM (information about of memory given to the programs during test is important, if programs used hashing)
VKSACH is slower than POPEYE in problems with promotions (or possibility of promotion) of white pawns, but faster in problems with promotions of black pawns.
POPEYE - in intelligent mode is solution 2x faster if used only default option (2MB) than if used option -maxmem 100M !!! Of course, without intelligent mode is faster with more memory. This paradox with long clearing of hash memory exist also in Alybadix.
