[petsc-users] petsc 3.4.3

[Barry Smith]

  We'd need more specific details on why it is slower than you think it should be. Is the it built with optimization (i.e. ./configure --with-debugging=0) ? Are the solvers converging with more iterations than expected http://www.mcs.anl.gov/petsc/documentation/faq.html#newton http://www.mcs.anl.gov/petsc/documentation/faq.html#kspdiverged ? Is the machine perhaps not suitable to for the simulations http://www.mcs.anl.gov/petsc/documentation/faq.html#computers?
