Are your tablebases on your hardrive?.
This 40 secs is FAST. On my cel 433 takes 5:25 to see it.
But why is yours at depth 14/34 mine at 15/35?
That was with H732 tablebase as was using the F6 disc in
my other tourney as the tablebase, but now curious so With F6
Original disc installed using Tablebase from the CD.
I get slightly faster but much fewer tablebase hits.
Maybe it's just my E drive speed compared to my D which has just broken.
But both these results were with the CD in my E drive, both setup from
new position.

How do you change the tablebase depth?.
