I've written a couple of my own, including a fairly intensive 3D FEM 
solution that was part of an iterative loop. After we replaced some bits 
of Fortran-like code with more natural Mathematica, the speed was 
similar to a fully compiled code. Ultimately, you can't compete with a 
large scale commercial FEM because of things like memory management, but 
for special purpose analysis, by all means go for it.
