Hi,All! when using AMS_BiCGSTAB to solve a matrix equation,I found that the setup time accounts for 77% as shown in the figure .Is this normal or could it be that I did something wrong? Is there any hope of reducing the time in this aspect,? I hope to receive your assistance or suggestions.

Thank you.
