It is indeed. Many engines have a hard time, I wonder why.

This surprised me. Did you use an older version of Yace here? I tried Yace
Paderborn on my 486DX-50, 4 MB RAM and it needed about 19 minutes.
8127562 19:12.7 Mat06 10++ 1.Nc3 e3 2.Ne4 d6 3.Rxd6H Bxf4H 4.gxf4H {HT}
{30}
8185987 19:17.5 Mat04 10t 1.Nc3 e3 2.Rb5 d6 3.Nd5 Bxf4H 4.Nxf4#H {-50}
8278467 19:23.7 Mat04 10. 1.Nc3 e3 2.Rb5 d6 3.Nd5 Bxf4 4.Nxf4# {-50}
So on your faster computer it should be a piece of cake.
