[Help-gsl] gsl vs. petsc

While I've used petsc for some larger numerical linear algebra projects 
(typically on the order of 10000 degrees of freedom), I'd thought that smaller 
problems, with sizes of <= 100 degrees of freedom could be well handled by 
serial algorithms.  But petsc obviously has a much more extensive collection of 
solvers for sparse systems.  I was wondering, has anyone compared performance 
between the two libraries on smaller problems?
