Anyway takes my rebel10 c strongest settings 10 secs to see it, 19 secs on cel 433a 64mb ram to post the line. Line at 19 secs 1.. Bb5 Bxb5 2.. Qxh5 g5 3.. Be3xg5 f6xg5 4.. Rg1xg5+. Rebel 9 same machine. Takes exactly the same time to see the exact same line. Maybe you are looking at line C score for your 1.17 not line A time? since I get at 1.09 mins with sys tiger on rebel 10 a line score of 1.17 with the line you produced.
