[Dune] Performance of vertex paramter from DGF file

[Patrick Leidenberger]

Hi all,

my code uses the element parameters from the dgf file. I read them like
shown in dune-grid/grid/io/file/dgfparser/main.cc.

Is it possible, that the access to the parameter is very slow?

It costs me ca. 4 minutes to get 1 parameter per element from a file
with 100k elements.

To get the id of every surface of a tetrahedron form all that elements
cost less then 1 second.


-> for Markus: the new istl<->trilinos benchmark will come as soon as my
code runs again....


Best regards

Patrick
