Here is a report of the first 5 positions (I think the 1st position gave an error or something) from your testsuite, each run with 120 seconds, 16 cores and 4096 MB hash (it doesn't go any higher):
"WAC.001"; Smove: Qg6 Stime = 0.18 Right = 1/1 Total NPS = 135126 <sol.time> = 0.18
"WAC.002"; Smove: Rxb2 Stime = 0.17 Right = 2/2 Total NPS = 24549300 <sol.time> = 0.175 <depth> = 46 <time to depth> = 120
"WAC.003"; Smove: Rg3 Stime = 0 Right = 3/3 Total NPS = 21178724 <sol.time> = 0.117 <depth> = 43 <time to depth> = 120
"WAC.004"; Smove: Qxh7+ Stime = 0 Right = 4/4 Total NPS = 21177858 <sol.time> = 0.0875 <depth> = 43 <time to depth> = 120
"WAC.005"; Smove: Qc4+ Stime = 0 Right = 5/5 Total NPS = 21176982 <sol.time> = 0.07 <depth> = 43 <time to depth> = 120
Thanks, Martin! This is very interesting. Comparing to the 1 and 4 core runs on my machine, and making a rough correction for core speed (appears to be about the same)... it looks like positions 2 and 3 gain an average of 5.5 plys in going from 1 to 16 cores, and 2.5-3 plys going from 4 to 16 cores. So at least with these two tactical positions, the scaling up to 16 cores is not as bad as I feared.
Note that the other positions are short mates, so they don't affect the statistics reported by the testsuite command. In fact this is why the first position appears to give an error... the statistics can't be computed properly from a short mate. I've been meaning to correct my testsuite command for this.

P.S. I'll also add expanding the hash limit to my ToDo list.
Here is my test EXchess 7.01b versus Delfi 5.4.
+58 ELO points over Delfi 5.4 engine !!!. The previous version (6.71b) was only +8 ELO over Delfi 5.4.
Delfi 5.4 1 CPU has 2683 ELO points in CCRL_4/40. So, I suspect EXchess 7.01b w32 1CPU to have around 2740 ELO CCRL_4/40
A nice enhancement (+50) of this superb and novative chess engine over the previous version !
Do you (still) remember the old ChessBase native versions of EXchess ? I have from years all these engines. What a joy !
This means progress ! This means a true original author & engine ! Reception Houdinello Futurello ? Bravo, Mr.Homan !
thanks! , works very well under FritzGUI. Under Shredder GUI, it does not work, ExChess makes no move.

Hi Günther,
just installed the engine inside Shredder 12 GUI using the wb2uci.eng from this thread.
Here the engine is running ok
Hello !
Works very well in all GUIs supporting only the UCI protocol (HIARCS Chess Explored add-in) ! For all these GUIs the UCI recognized engine is the Wb2UCI.exe (in fact it is only a communications translator engine-gui, nothing more).
Important are the commands comming from the Wb2Uci.eng file .Essential (and particular for its architecture) for a good function of EXchess are: Edit=setboard (the winboard method that use a fen-string) and LevelExtend=Progressive (the engine treat the level command in the middle of a game as a start point for a new counting of moves ) - without this command the engine plays very quickly all the moves.
