Dear Sir/Madam,<div> Lately, I read there is a optimized version of PETSc by using '--with-debugging=0'. I have two questions here:</div><div>1, Do I need to use '/config/configure.py ... --with-debugging=0' when I configure the PETSc in order to use the non-debugging version of PETSc? Therefore, if I want to switch PETSc between these two versions, I have to keep configuring. </div>
<div>2, I was using the '--with-debugging=0' to configure the PETSc. However, I tested the computational rate by executing the ex29.c. The non-debugging version does not improve the speed much; in the contrary, it slow down the speed a little bit. The comparison is attached here. Any idea on this.</div>
<div><br></div><div>thanks in advance,</div><div>Alan</div><div><br></div>
