It turned out to be a stupid operator error. I wanted to set EGTB-cache to 16
MB. But I had set it to 16 bytes. This made TBs go crazy. Actually, I should
already have been suspicious because of the too good nodes/s (over one million)
in a position with many TB-accesses. Now it runs less than half that fast.

Sorry for my nonsensical first post.

Dieter
