ok. we'll try your pool. What mean these numbers in dashboard:

1. Own: valid shares - 39,712,994
          invalid shares - 731,291
           Efficiency      - 98.2%

2. Pool: valid shares - 64,235,849
          invalid shares - 39,068,743
           Efficiency      - 62.25%

Why so many wrong pool shares ? As we can see, more than half, and the blocks even in solo were find approximately every hour or two, and here at a speed twice more than in solo, blocks no find in 3,5 h
